java.lang.OutOfMemoryError: Java heap space

[devaraj s, modificado 10 Anos atrás.]

All,
We are running liferay 6.1 ce ga2 in existing jboss 7 server (www.xxx.com) and we have other webapplication in the same jboss server (www.xxx.com/appname).

We have running these two application since from long days back. it was working fine. Now its throwing outofmemory error.

here is my JAVA_OPTS configuration

set "JAVA_OPTS=%JAVA_OPTS% -Xms512M -Xmx1024M -XX : PermSize=256M -XX:MaxPermSize=512M"

I have not set file encoding, prefered protocol stack in JAVA_OPTS , I hope obsence of these paratmeters in JAVA_OPTS does not related to outofmemeory error.

here is my full stack trace

Hi

Add JAVA_OPTS in your system variable with following options:

Steps in windows7:

Right click on Mycomputer--> Advanced System settings -->environment variables -- > under system variable add the following

variable name:JAVA_OPTS
variable value: -Xms256M -Xmx512M
Thanks,
Ramakanth

Hi , Thanks for response.

I followed your suggestion but no useful , I think there is some other issue.

It is possible to increase heap size allocated by the JVM by using command line options Here we have 3 options
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xss<size> set java thread stack size
java -Xms16m -Xmx64m ClassName

In server
java -Xms16m -Xmx64m ClassName
Open the server tab in eclipse
right click open
click on open lauch configuration
Go to arguments
Here you can add in VM arguments after endorsed
-Xms64m -Xmx256m

It is possible to increase heap size allocated by the JVM in eclipse directly In eclipse IDE goto
Run---->Run Configurations---->Arguments
Enter -Xmx1g(It is used to set the max size like Xmx256m or Xmx1g...... m-->mb g--->gb)
In JBoss
You can set it as JVM arguments the usual way, e.g. -Xms1024m -Xmx2048m for a minimum heap of 1GB and maximum heap of 2GB. JBoss will use the JAVA_OPTS environment variable to include additional JVM arguments, you could specify it in the /bin/run.conf.bat file:
set "JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx2048m"

Dear Devraj,

I am having same environment setup and also facing the same errors.
Please share in case you have got solution to this error.

Thanks,
Vishal

Could you please check by increasing heap size from 512 to 1024 and verify once
