I am having a weird, sporadic and impossible to duplicate problem. If this is not the correct forum, I apologize and would appreciate a shove in the right direction.

My configuration is 4 JBoss nodes clustered and running behind the Apache mod_jk load balancer.

Server Version: Apache
JK Version: mod_jk/1.2.25

Release ID: JBoss [Trinity] 4.2.3.GA (build: SVNTag=JBoss_4_2_3_GA date=200807181417)

Java VM: Java HotSpot(TM) Server VM 1.5.0_17-b04,Sun Microsystems Inc.
OS-System: Linux 2.6.18.2-34-default,i386

Like most JEE apps, I use the HttpSession to persist user level data across HttpRequests.

My delimma is that in some cases, a user will see another users data. It is almost as if the JSessionID is getting mixed up. Has anyone seen this before?

Any ideas on where to start?

Thanks in advance!
