Do you have any feedback on this issue? We are planning to go production with LINUX /JBOSS 3.2.2 in a clustering env. I wish to get a feedback ASAP.
FWIW - this is configuration (Linux/JB 3.2.2) what we are on in production. We have Apache/JK2 in front of two 3.2.2 cluster nodes, using sticky sessions, and it's working well. The only problem we have is that automatic/seamless failover of sessions doesn't seem to work, as it seems the subject/principal on the session does not get replicated with the session. It just means that, if a node goes off the air, users will see a login screen on the next page request, for the node that JK2 sends them to.
Re: the memory problem in the first post above - what do you mean by 99% utilized? System RAM? Stack? Seems like a leak somewhere. It's surprising a profiler can't find it.
