We are running Shark on JBOss (EJB mode).

It is running 24/7.

Usually after about 10 days we need to reboot the whole server because we
get an out of memory error.

*
Caused by: java.lang.OutOfMemoryError: PermGen space
*** Caused by:
org.enhydra.xml.xmlc.XMLCRuntimeException:
java.lang.reflect.InvocationTargetException


*We increased the JVM memory but still get the issue.

We seed about 10-30 new processes every day.


Anyone else who encoutered this problem and solution other then rebooting
every 10 days?
