Guidance on troubleshooting org.ldaptive.pool.BlockingConnectionPool issue

[Ray Bon]

Mike,

'kill' is a 'nix command. You want the thread dump from the jvm that is running jetty.
You could try visualvm.

I don't believe we have any JVM core dumps. I'm assuming we'd need to generate it when in the midst of the pegged CPU condition? If so, is that the "kill -3" technique or something else?


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
