OutOfMemoryError

[zhisheng xie <xi...@gmail.com>]

Dear Sir

       I encountered a turbine problem in my project,  attached please found
bellow.  My project runs on WebSphere environment,  the exception occurs
frequently everyday, the turbine service is down once the exceptions occurs
several times. I need to restart WebSphere service to start my project.
Could you please tell me the possible reason and give me a solution?


Thank you very much


Regards,

Zhisheng Xie

Re: OutOfMemoryError

[Thierry Randrianiriana <ra...@gmail.com>]

Hi,

Try to optimize your JVM to use a more memory by default with these options:

-server       to select the "server" VM
-Xms<size>        set initial Java heap size
-Xmx<size>        set maximum Java heap size
-Xss<size>        set java thread stack size

java -server -Xms<size> -Xmx<size> -Xss<size> ...


Regards,
