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: 2004-02-02 07:47:14 StandardManager[/dirServices] [InMemoryReplicationManager] processsExpire: Exception during session expiration java.lang.StackOverflowError at org.apache.catalina.session.ReplicatedSession.expire(ReplicatedSession.java:148) at org.apache.catalina.session.ReplicatedSession.expire(ReplicatedSession.java:179) at org.apache.catalina.session.StandardSession.expire(StandardSession.java:608) at org.apache.catalina.session.ReplicatedSession.expire(ReplicatedSession.java:149) at org.apache.catalina.session.ReplicatedSession.expire(ReplicatedSession.java:179) at org.apache.catalina.session.StandardSession.expire(StandardSession.java:608) at org.apache.catalina.session.ReplicatedSession.expire(ReplicatedSession.java:149) at org.apache.catalina.session.ReplicatedSession.expire(ReplicatedSession.java:179) Has any one had that problem or a similar one before?
