I missed another opportunity to collect info during a lockup as I tried a
"kill -3" and found that didn't dump any info anywhere that I could find.
After digging around some more, I found that with Tomcat, that would show
up in catalina.out, but we're running on Jetty. The Jetty log dir was empty.

I searched some more, and I think I found that this would work for Jetty:
sudo -u shibidp jstack [PID] > threaddump.log

Any additional pointers on getting a useful thread dump? Ideas on where
"kill -3" might have dropped its data?

Thanks,
Mike
