We have configured the CAS server on tomcat 6, with oracle coherence
clustering for the tickets. The registry job gets kicked every few minutes
and cleans up the expired TGTs. Over a period of time, the application
starts throwing java.lang.OutOfMemoryError: PermGen space exception.
Exception stack trace is given below. Can someone share their experience
with clustering & memory issue ?
