Seam out of memory error
Hi,
I am experiencing out of memory errors in my seam application. It looks like I get the error when JBoss tries to passivate my stateful session beans. I have some stateful session beans which have DataModel annotation which is a list of objects. I did not mention the scope of the bean so I think it is default to conversation scope? I get error when the jboss tries to passivate these stateful beans. Any idea what can i do to get rid of this problem? I am using these memory settings in my jboss:
-Xms640m -Xmx1408m -XX:PermSize=256m -XX:MaxPermSize=512
Here is the stack trace:
