are there other versions of Apache Tomcat running in the same cluster?
Check the logs for what members are joining the cluster, then check what
version they are
best

Hi,
I have an exception when one on my Tomcat nodes restarts. The session are not synced and user complain about being logged out. I was
running 6.0.32 and had the problem. Now I'm running a custom build of 6.0.33 from yesterday. I added a little code which prints ' SEVERE:
name=user'. The key on which the sync fails while reading the value.
I looked into the java code in ObjectInputStream and it looks like some
inconsistency in the ObjectStream.
I have 4 nodes on Debian 5, sun-java6-jdk 6-22-0lenny1, seen the problem on Tomcat 6.0.29, 6.0.32 and a custom build 6.0.33. I can't
reproduce this (yet) on my test environment, so debugging it is difficult without upset customers.

Can I provide more information? Where should I look.
NB: In some previous mails about another problem I thought that might be the
reason for my logout problem, that is why I tried 6.0.33-dev.
Ronald.
