3.2.3 crashing and hanging unpredictably

We recently began experiencing crashing and hanging of JBoss 3.2.3 in our production environment at unpredictable time intervals--anywhere from 30 minutes to 12 hours after re-running the app. This began after we upgraded our mysql connector from 3.0.6 to 3.0.10, and made several minor application changes. We have sinced rolled back all of those changes, but continue to experience the same crashing and hanging. Sometimes it hangs with one CPU maxed out, sometimes it hangs with both CPUs idle (we have a two CPU machine). Sometimes it kills itself with no core dump and no trace in the logs, and sometimes it kills itself by shutting itself down and printing this to server.log:

Our configuration is like this:
JBoss 3.2.3
java version "1.4.2_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
Java HotSpot(TM) Client VM (build 1.4.2_03-b02, mixed mode)
Linux version 2.4.21-4.0.1.ELsmp (bhcompile@bugs.devel.redhat.com) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-20)) #1 SMP Thu Oct 23 01:21:42 EDT 2003
mysql-connector-java-3.0.10-stable-bin.jar
mysql Ver 11.18 Distrib 3.23.58, for redhat-linux-gnu (i386)
This configuration had worked fine for us (except using the 3.0.6 mysql connector) for several weeks without incident.
 
Don't get me started about those stupid light bulbs.
