Every few days, the Jenkins UI hangs and becomes totally unresponsive, i.e. "Jenkins is not picking up HTTP requests, so all attempts to connect hang and no page is ever rendered."
It doens't seem to be connected with a certain job getting started or anything.
I couldn't get a thread dump from the UI, nor from jstack, only from jstack -F. I could get the jmap -heap, but not the full heap dump. Both outputs are attached. If I understand that right, we are in a GC spiral.
Is there anything I can do to help debugging this?
