Subject: Tomcat 4.x + session replication (javagroups) = StackOverflowError
Hi,
We're using javagroups for the session replication between our 2 clustered
Tomcat 4.x servers. And we're having the following problem:
When we start one of the servers, its CPU usage hit 100% (as if there were a
never ending loop). It looks like it's trying to read a big number of old
persisted session. Then, while invalidating them, it's having a problem. We
turned the javagroups debugging on and that's what we get in the logs:

processsExpire: Exception during session expiration

Has any one had that problem or a similar one before?
Any comment will be greatly appreciated,
Thanks,
