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:
sudo jstack -F 56400
Attaching to process ID 56400, please wait...
