jboss stops responding due to Out of Memory error

[smikrish]

Hi ,
I have an application running on jboss.But the jboss seems to stop responding after 2 days of running continously throwing an out of memory error.
For the same i increased memory to 512 Mb as follows
java $HOTSPOT $JAXP -Xms128m -Xmx256m -classpath $JBOSS_CLASSPATH org.jboss.Main $@

Also increased the number of system threads by changing file jboss-service.xml in jboss-4.0.1\server\default\conf\
i set the MaximumPoolSize(number of threads in pool) to 25 from 10

Is there anything else i can do to avoid jboss going to non responding state?

Thanks
SmiKrish

If you are running on Unix/Linux, look into increasing the file descriptor setting for the OS.

Sounds like one of the applications that you have deployed is leaking memory. Until you fix the leak, expanding the heap size will only delay the out-of-memory error.
