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.

I have changed the variable limit for java in environmental factors several times, I've adjusted maximum server ram usage in run.bat and still no luck.
Three different launches at different values include
C:\WINDOWS\system32>java -Xmx4000M -Xms512M -jar C:\Users\cavem\OneDrive\Desktop\RLCraft+Server+Pack+1.12.2+-+Beta+v2.8.2\forge-1.12.2-14.23.5.2854.jar nogui

If I give the program to much memory it doesn't start, if I give it to little it doesn't start. Any ideas as to what my problem may be? I changed the file to include complete location after receiving errors regarding not being able to find the file upon booting the server (running java and run.bat in administrator hasn't helped either).
Looks like you are using a 32-bit JVM, install a 64-bit JVM will work.
I have currently been trying to setup a minecraft server on an Intel Nuc that I have it has 8gb of ram this will be important later. I used to be running it on my main desktop and was able to tun it with 4gb of ram allocated to it, that computer had 16gb of ram though. My initial problem was that I could not allocated more than 1500M of ram to it using the following command in a .bat file;
java -Xms2048M -Xmx2048M -jar server.jar
I then decided to run it in command prompt and received the following error.
java -Xmx2048M -Xms2048M -jar server.jar nogui
Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap
I did some research on the error and found that I might need to add a system variable for.
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
So I did that and it still didn't work.
Then I decided to install 64bit Java as I did not know if I had it or not and that is when I received the error;
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
So after that i tried to figure out which version I had so I ran the command;
java -version
and received this:
Picked up _JAVA_OPTIONS: -xms512M
Unrecognized option: -xms512M
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Whenever I try to run any Java commands or the server this is what I get and this is after I had removed the system variable.
I am not super knowledgeable about Java and I am just trying to run a minecraft server so if you need any more information please ask.
Thanks for all of the feedback but I got it working it turns out I just needed to restart a few times and uninstall the version of Java I had and get 64-bit Java. Also if your still curious I am running windows on the NUC
i am student and i am try to install apache spark on Ubuntu when ever i try to
built spark through sbt with sbt/sbt assembly command i find this error
i have already try to maximize the size of the heap still have not found
solution to this issue kindly help me through this issue.
the error i found
Attempting to fetch sbt
Launching sbt from build/sbt-launch-0.13.7.jar

Check out this article:

Sometimes when you attempt builds and you don't have enough heap allocated it will bomb out, hence, in the example they increase heap size on the command line before running HelloWorld:
java -Xms64m -Xmx256m HelloWorld
I have a maven project I want to run it using 64 bit jvm in the project run configuration under VM arguments I set the following
-vm C:/Program Files/Java/jdk1.8.0_60/bin
It says Unrecognized option -vm
Can anyone tell me how to set jvm from VM arguments?
Thanks
As you highlighted in one of your comments, after changing JAVA_HOME to another VM, you are getting a error message saying:
Error occurred during initialization of VM
Could not reserve enough space for 1945600KB object heap
The problem here is that some configuration is setting the -Xms argument to something around 2G or 2048M. Look into your run configuration and remove that setting. If you are experiencing OutOfMemoryError: Java heap space, look at this answer.
Hello I have got problem I was reading about some solutions and tried some of them and they helped a little. When i was starting Jboss Developer Studio or Eclipse Luna (32bit) I had error could not create Java Virtual Machine. Then in system environment I added _JAVA_OPTIONS with New Variable Value: -Xmx512M and this helped a bit: Now i can run Jboss Developer Studio and Eclipse but when i Start Server in JBoss Developer studio it still gives error:
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified
Picked up _JAVA_OPTIONS: -Xmx512M
I dont know how to solve it. I was looking for reason in Internet and trid a few more things but they didnt help.
I will be very thankful for every help.
I have repaired it by adding in System Environment Variables
_JAVA_OPTIONS
-Xmx512M -Xms64M -XX:MaxPermSize=512m
And then changing options in \jbdevstudio\runtimes\jboss-eap-6.3\bin
appclient.conf.bat
rem # JVM memory allocation pool parameters - modify as appropriate.
set "JAVA_OPTS=-Xms64M -Xmx512M -XX:MaxPermSize=512M"
Now everything works for me.
