I am running a Java application in a Linux Server with 32GB of memory and suddenly the application stopped working and returned this error in a log file. At the moment of the exception there was still about 25GB of memory available.
These were the details at the moment of the crash:

This message contains some possible solutions. But instead of trying each one of those solutions and cross my fingers for it to no happen again, I need to determine the exact reason why this OutOfMemory happened, try to reproduce it again and apply the correct solution.
I am starting an Apache Felix instance and the command line I use to start the java app is:
java -Dorg.osgi.framework.bootdelegation=sun.*,com.sun.* -Dfile.encoding=UTF-8 -jar bin/felix.jar &
My command line java program works when run on a Windows 10 workstation with a dual core CPU with 1GB RAM allocated.
However, it encounters an out of memory error when I run it on a Ubuntu virtual machine with four vCPUs with 12GB RAM.
Both are run using -Xms and -Xmx set accordingly to the same value.
This is a strange error.
UPDATE:
1) I can't share the code and not to sound arrogant or anything but I think there is nothing wrong with the code.
2) The error is as follows:
#

Btw, my vm's max memory is 12GB and I used -Xms12160m -Xmx12160m.
As for my workstation, my max memory is 2GB but I used -Xms1024m -Xmx1024m
So it seems to me on the Linux system you are asking it to reserve the full 12 MBs as the initial heap size; this is not really practical as it obviously needs memory for other stuff (code, operating system etc).
From other questions on SO it seems clear that the defaults for minimum is something like 1/64th of the physical RAM.

Question
why different work ?
how to solved that ?
I try that (not solve)
set memory
java -Xms2g -Xmx2g
i solve thaht.
"setsebool -P httpd_execmem on"
My Tomcat server has been running for several days, but I can't shut it down normally because when executing shutdown.sh, I got this error:

Therefore I have to kill Tomcat in order to shut it down. But the weird thing is that Tomcat worked normally when this error is generated(It can process web request normally).
Here are the VM options:
-server -Xms1G -Xmx1G -XX:+UseG1GC
My server has 2GB memory. Could anyone figure out what's happening?
Thanks!!
This looks like you are setting your memory configuration by:
JAVA_OPTS="-server -Xms1G -Xmx1G -XX:+UseG1GC"
The JAVA_OPTS environment variable is used for all of Tomcat's java processes such as the one that is used to send the shutdown message.
You need to be certain that you are configuring your Tomcat memory by setting:
CATALINA_OPTS="-server -Xms1G -Xmx1G -XX:+UseG1GC"
This setting will then only be applied to the Tomcat process. The other control processes will execute fine using default memory settings.
I have a java file which is being triggered from a shell script. If I execute the shell script at command line it is executing the java file without any issues but if i execute this shell script from browser( i have a index.php which executes this shell script in linux server ) it is not executing the java file in shell script. The shell script is executed properly If I remove the java execution line from the shell script.
below is the error i received when executed from browser.

Please help me on how I can fix this problem.. Stuck with this issue from last one week. :|
Permission problem.
Probably you run this java file as a different user from a browser.
An error report file with more information is saved as: # /tmp/hs_err_pid306.log
What does this error say?
Issue you have is with the HEAP memory.You don't have set enough memory to run the application.
Default size of Heap space in Java is 128MB on most of 32 bit Sun's JVM but its highly varies from JVM to JVM e.g. default maximum and start heap size for the 32-bit Solaris Operating System (SPARC Platform Edition) is -Xms=3670K and -Xmx=64M and Default values of heap size parameters on 64-bit systems have been increased up by approximately 30%. Also if you are using throughput garbage collector in Java 1.5 default maximum heap size of JVM would be Physical Memory/4 and default initial heap size would be Physical Memory/16. Another way to find default heap size of JVM is to start an application with default heap parameters and monitor in using JConsole which is available on JDK 1.5 onwards, on VMSummary tab you will be able to see maximum heap size.
By the way you can increase size of java heap space based on your application need and I always recommend this to avoid using default JVM heap values. if your application is large and lots of object created you can change size of heap space by using JVM options -Xms and -Xmx. Xms denotes starting size of Heap while -Xmx denotes maximum size of Heap in Java. There is another parameter called -Xmn which denotes Size of new generation of Java Heap Space. Only thing is you can not change the size of Heap in Java dynamically, you can only provide Java Heap Size parameter while starting JVM. I have shared some more useful JVM options related to Java Heap space and Garbage collection on my post 10 JVM options Java programmer must know, you may find useful.

If it's tomcat you have to set this Memory Variables in "catalina.sh".
Eg : If you a starting the application through command Line :
/bin/java -Xms2048M -Xmx2048M Djava.util.logging.config.file= -Xms2048M -Xmx2048M
