Tomcat hung
I continually get tomcat in this state and can only recover by restarting tomcat from the command line. Here is the stack trace that I gathered while getting into this state, but it does not make any sense to me.
Tomcat version apache-tomcat-6.0.26
OS linux
Jstack trace on tomcat hang.
Tomcat is not responding, nor any webapps. Profiler will not attach
Attaching to process ID 21989, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 10.0-b19
Deadlock Detection:
No deadlocks found.

Yes, it was identifying it just as 10.0-b19 that was confusing.
You might want to upgrade, since 1.6.0_05 is quite old and lots of fixes have gone in since then.

No idea what JVM that is; strongly suggest you install a real one (e.g., 6u22) and see if the problem goes away.
What happens if you run Tomcat directly, not under control of the IDE?

Re: EXTERNAL: Re: Tomcat hung

In your full production trace, is there an indication which thread has
the "<0xd50244e8>" lock?
I've debugged similar situations where threads were "blocked waiting
for monitor <0x.....>" (getting java.sql.Connections, as it turned
out) -- identifying & examining the thread that had locked that
monitor (with a message something like "grabbed monitor <0x....>")
helped quite a bit w/debugging.

Production or testing?
Are these the only threads?
What happens if you jstack without attempting to connect a profiler?
