I am facing a problem with Intellij 2019.2.1 version to which I recently upgraded. I have set up the Xms and Xmx in the Intellij Help -> Edit Custom vm options and I have also manually set up the same properties in idea64.exe.vmoption and idea.exe.vmoption as well. like below :-
-Xms128m
-Xmx10g
Now, when I am starting my application, in the VM argument of the application I am passing -Xmx800m then on runing the application it throwing an error stating that "Initial heap size set to a larger value than the max heap size".
Could some one please suggest what wrong configuration I am putting here or am I missing something.
IntelliJ IDEA VM options (Help | Edit Custom VM Options) have no effect on the VM options of the apps you start from IntelliJ IDEA. These are only for the IDE runtime JVM, not for your own apps that you develop.
Post a screenshot of the run/debug configuration showing the VM options field. What type of the configuration is that? It's possible that you have defined global system environment variables that set the initial heap size to some large value (-Xms). Make sure you don't have _JAVA_OPTIONS and JAVA_TOOL_OPTIONS environment variables set. If you do, remove them and logout/login or reboot for the changes to apply.
If the project is imported from Maven and you are running tests, pom.xml may supply the VM options, search pom.xml for for -Xms and either remove this option or make it lower than -Xmx.
If the project is Gradle based and you run it via Gradle, the options you have defined in gradle.properties via org.gradle.jvmargs will have effect. Make sure you don't override -Xms there. You can also switch to IntelliJ IDEA run option to not use Gradle options.
I am getting the following exception repeatedly each time I try to run the program.
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
I tried to increase my virtual memory (page size) and RAM size, but to no avail.
How can I eliminate this error?
Run the JVM with -XX:MaxHeapSize=512m (or any big number as you need) (or -Xmx512m for short)
This can also be caused by setting something too large on a 32-bit HotSpot vm, for example:
-Xms1536m -Xmx1536m
where this might/would work:
-Xms1336m -Xmx1336m
here is how to fix it:
Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System
Variables->New: Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
Variable name: Path
Variable value: %PATH%;C:\Program Files\Java\jre6\bin;F:\JDK\bin;
Change this to your appropriate path.
I ran into this when using javac, and it doesn't seem to pick up on the command line options,
-bash-3.2$ javac -Xmx256M HelloWorldApp.java
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
so the solution here it so set _JAVA_OPTIONS
-bash-3.2$ export _JAVA_OPTIONS="-Xmx256M"
-bash-3.2$ javac HelloWorldApp.java
Picked up _JAVA_OPTIONS: -Xmx256M
And this compiles fine.
This happens to me on machines with a lot of RAM, but with lower memory ulimits. Java decides to allocate a big heap because it detects the ram in the machine, but it's not allowed to allocate it because of ulimits.
32-bit Java requires contiguous free space in memory to run. If you specify a large heap size, there may not be so much contiguous free space in memory even if you have much more free space available than necessary.
Installing a 64-bit version of Java helps in these cases, the contiguous memory requirements only applies to 32-bit Java.
Combined with -Xmx512M use -d64 to make sure you're running 64-bit VM. On a 64-bit machine I thought for sure I was running 64-bit virtual machine, but no. After installing 64-bit Java the -d64 option works and -Xmx allows much larger memory sizes.
java -d64 -Xmx512M mypackage.Test
Open gradle.properties file in android folder.
Replace this line:
org.gradle.jvmargs=-Xmx1536M
with:
org.gradle.jvmargs=-Xmx512m
Explanation:
Max limit from Gradle document:
If the requested build environment does not specify a maximum heap size, the Daemon will use up to 512MB of heap.
I got the same error and resolved this by configuring it in the run.conf.bat
Run the JVM with the configuring run.conf.bat in Jboss5x
If free memory is not available AS you are passing in the statement then please make changes in run.conf.bat
set "JAVA_OPTS=-Xms512m -Xmx512m -XX:MaxPermSize=256m"
I had similar issues. I had installed 32 bit version of Java on a 64 bit machine.
By uninstalling that version and installing 64 bit version of Java. I was able to resolve the issue.
I know there are a lot of answers here already, but none of them helped me. In the end I opened the file /etc/elasticsearch/jvm.options and changed:
-Xms2G
-Xmx2G
to
-Xms256M
-Xmx256M
That solved it for me. Hopefully this helps someone else here.
Suppose your class is called Test in package mypackage. Run your code like this:
java -Xmx1024m mypackage.Test
This will reserve 1024 MB of heap space for your code. If you want 512 MB, you can use:
java -Xmx512m mypackage.Test
Use little m in 1024m, 512m, etc
Sometimes, this error indicates that physical memory and swap on the server actually are fully utilized!
I was seeing this problem recently on a server running RedHat Enterprise Linux 5.7 with 48 GB of RAM. I found that even just running
java -version
caused the same error, which established that the problem was not specific to my application.
Running
cat /proc/meminfo
reported that MemFree and SwapFree were both well under 1% of the MemTotal and SwapTotal values, respectively:
MemTotal: 49300620 kB
MemFree: 146376 kB
...
SwapTotal: 4192956 kB
SwapFree: 1364 kB
Stopping a few other running applications on the machine brought the free memory figures up somewhat:
MemTotal: 49300620 kB
MemFree: 2908664 kB
...
SwapTotal: 4192956 kB
SwapFree: 1016052 kB
At this point, a new instance of Java would start up okay, and I was able to run my application.
(Obviously, for me, this was just a temporary solution; I still have an outstanding task to do a more thorough examination of the processes running on that machine to see if there's something that can be done to reduce the nominal memory utilization levels, without having to resort to stopping applications.)
Error :
For the error, "error occurred during initialization of vm could not reserve enough space for object heap jboss"
Root Cause :
Improper/insufficient memory allocation to our JVM as mentioned below.
e.g. JAVA_OPTS="-Xms1303m -Xmx1303m -XX:MaxPermSize=256m" in jboss-eap-6.2\bin\standalone.conf or "JAVA_OPTS=-Xms1G -Xmx1G -XX:MaxPermSize=256M" in jboss-eap-6.2\bin\standalone.conf.bat which is nothing but JVM memory allocation pool parameters.
Resolution :
Increase the heap size. To increase the heap size,
goto -> jboss-eap-6.2\bin\standalone.conf.bat or jboss-eap-6.2\bin\standalone.conf
change ->JAVA_OPTS="-Xms256m -Xmx512m -XX:MaxPermSize=256m" where -Xms is Minimum heap size and -Xmx is Maximum heap size.
Usually its not recommanded to have same size for min and max.
If you are running your application from eclipse,
Double click on the server
select 'open launch configuration' you will be redirected to the window 'Edit launch configuration properties'.
In this windown goto the tab '(x)=Arguments'.
In VM Arguments, define your heap size as mentioned below
"-Dprogram.name=JBossTools: JBoss EAP 6.1+ Runtime Server" -server -Xms256m -Xmx512m -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true
I recently faced this issue. I have 3 java applications that start with 1024m or 1280m heap size.
Java is looking at the available space in swap, and if there is not enough memory available, the jvm exits.
To resolve the issue, I had to end several programs that had a large amount of virtual memory allocated.
I was running on x86-64 linux with a 64-bit jvm.
I had right amount of memory settings but for me it was using a 64bit intellij with 32 bit jvm. Once I switched to 64 bit VM, the error was gone.
If you're running 32bit JVM, change heap size to smaller would probabaly help. You can do this by passing args to java directly or through enviroment variables like following,
java -Xms128M -Xmx512M
JAVA_OPTS="-Xms128M -Xmx512M"
For 64bit JVM, bigger heap size like -Xms512M -Xmx1536M should work.
Run java -version or java -d32, java--d64 for Java7 to check which version you're running.
Assuming you have enough free memory and you setup you JVM arguments correctly, you might have a problem of memory fragmentation. Check Java maximum memory on Windows XP.
Anyway, here is how to fix it:
Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System Variables->New:
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
OR
Change the ant call as shown as below.
<exec
**<arg value="-J-Xmx512m" />**
</exec>
It worked for me.
Error occurred during initialization of VM
Could not reserve enough space for 1572864KB object heap
I changed value of memory in settings.grade file
1536 to 512 and it helped
Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System Variables->New:
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
In case you are running a java program:
- run your program in a terminal using the correct command for linux it would be 'java -jar myprogram.jar' and add -Xms256m -Xmx512m, for instance: 'java -jar myprogram.jar Xms256m -Xmx512m'
In case you are running a .sh script (linux, mac?) or a .bat script (windows) open the script and look for the java options if they are present and increase the memory.
If all of the above doesn't work, check your processes (ctrl+alt+delete on windows) (ps aux on linux/mac) and kill the processes which use allot of memory and are not necessary for your operating system! => Try to re-run your program.
In CASSANDRA_HOME/bin/cassandra.bat you would find following configuration
REM JVM Opts we'll use in legacy run or installation
set JAVA_OPTS=-ea^
-javaagent:"%CASSANDRA_HOME%\lib\jamm-0.3.0.jar"^
-Xms**2G**^
-Xmx**2G**^
You can reduce 2G to some smaller number for e.g. 1G or even lesser and it should work.
Same if you are running on unix box, change in .sh file appropriately.
I got the same error and it got resolved when I deleted temp files using %temp% and restarting eclipse.
Sometimes it relates as
$ sysctl vm.overcommit_memory
vm.overcommit_memory = 2
If you set it to:
$ sysctl vm.overcommit_memory=0
It should work.
Replace -Xmx2G with -Xms512M or any greater memory size in cassandra.bat file in cassandra bin directory.
In my case I couldn't increase org.gradle.jvmargs=-Xmx... in gradle.properties beyond 1GB. It didn't work because I had two Java installation on my machine, one 32 bit (Gradle was using this one) and the other 64 bit. I resolved the problem by adding JAVA_HOME environment variable pointing to 64 bit Java.
No need to do anything just chnage in POM file like below
<configuration>
<maxmemory>1024M</maxmemory>
</configuration>
A few days I started getting this eror message when debugging my eclipse RCP:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I used to restart my stystem if that occured which fixed it but today even a restart didn't work anymore. Can anyone please give me a hint why this is suddenly appearing.
Those are the VM arguments I'm using:
-Dosgi.requiredJavaVersion=1.5 -Xmx2048m -Xms1024m -Dosgi.locking=none -XX:MaxPermSize=256m
Try to fix it with:
Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System Variables->New:
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
You are opening Eclipse by specifying 2GB of max memory and 1GB of min memory. And the message is telling you that there is not enough memory available to support that.
My issue was resolved after I reinstalled latest version of JDK.
Iam trying a Compiler in my java Eclipse. And I get the error :
Exception occurred during event dispatching:
java.lang.OutOfMemoryError: Java heap space
at java.awt.image.DataBufferInt.<init>(Unknown Source)
How to solve this?
Compiler compiles up to 185 files out of 414 files and then gets the exception. The memory is 1024M
Click on Run configuration in the Eclipse. Choose your application or server tab (which you want to have more memory size).
In the Argument tab, write -Xmx<memory size>. memory size is what you want to set.
set your Virtual Memory Argument
-Xms128M -Xmx1024M -XX:MaxPermSize=128M like this
I'm using Eclipse to run java program class, while I run it i got this error
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
then i changed the VM from the Properties > Run > VM Options, and I run the program again i got a new error,
Error occurred during initialization of VM
Incompatible initial and maximum heap sizes specified
I'm trying to apply stanford libraries in my program, any idea how to solve this error .
to change the VM for Eclipse you can change the amount of the MV from
Windows> Preferences> Java> Installed JREs
from there select the JRE and click edit, then write in the Default VM Arguments: to -Xmx1024M or any other amount of memory ...
Error occurred during initialization of VM. Incompatible initial and maximum heap sizes specified
This probably means that you supplied both -Xms and -Xmx options, and the -Xms (initial heap size) value is larger than the -Xmx (maximum heap size) value.
netbeans provide to change the -Xms only from Properties > run > VM options
I'm not a NetBeans user. However, a brief search of the Using NetBeans 5.0 manual says this is not correct:
Setting JVM Arguments
You can specify JVM arguments for the project in the Project Properties dialog
box. Open the Project Properties dialog box and click Run in the Categories pane
and then type a space-separated list of JVM arguments in the VM Options field.
In other words, you can set any JVM option that your JVM supports.
here is the string that i changed -Xms512m
(Finally he tells us!!)
Add -Xmx512m as well.
For the record, the common JVM options (such as -Xmx and -Xms) are clearly documented in the manual page for the java command. You should READ it CAREFULLY.
To enlarge the VM heap size use -Xmx option, this could solve the error. But it seems it's your coding problem. Perhaps code is in a dead loop to create new object, or a very large object is created in you code, so I suggest you to check code first.
