how to determine clustering problem?
We have a webapp that runs fine in 1 tomcat instance.
We have insured that all classes being stored in session are serializable
When I put the app into a cluster of 3 Tomcats on my machine, it kind of
works, but I am getting inconsistent failures. It is like constantly running
down rabbit holes as the errors change continually.
Is there a way to debug clustered apps? If this is a possible memory, issue,
How do I change the memory configuration for each Tomcat instance? Is there
a timeout for each screen request? can I configure it?

turn on logging, see Tomcat docs
then through log4j you can turn on logging for only
org.apache.catalina.cluster
and you will be able to see all messages going through.
