Donald Morton commented on JENKINS-23436 Jenkins Web UI Hanging Often Looks like the Tomcat folks figured it out using strace. I suppose you could do the same here? Run 'jstack ' to get the stacktrace. Find the thread with the Selector and get the 'nid'. Convert it from hex to decimal, and run 'sudo strace -f -p '. And see if the output looks like theirs?

Description:
I have several Jenkins nodes which go unresponsive during various parts of the day, I can bounce Jenkins from the command line to get things going again, or reboot the machine, but once it wedges again the Web UI never does come back without intervention.Here's a jstack of a recent such hang:
