Work Item web UI occasionally hangs

RTC RC4

We've had two cases where the web ui would hang after pressing Create
Work Item. Restarting the server fixes the problem. The catalina.out
file does not show any unusual problems. Any ideas on how to track
this down?

So it seems the 'server' is hanging not the UI right ?
If so, what we usually do is take java dump when the server is hung.
From the tomcat commandprompt you should be able to do CTRL+BREAK and it
will create a javacore
We usually do 3 of them, at 2 seconds interbal, to see if the thread is
very very slow or really hung

Does it help ?

I'll try to get some javacore files next time this happens. We are
running the server on AIX, and as I recall you have to send the process
a SIGABRT to get the javacore. Does that sound right?

Bryan

Ah, yes... umm or a kill-3 ?
