We have a Jenkins instance with ~50 jobs on it. They are all using maven to build...some are Android projects and others are pure Java. Our box frequently becomes completely unresponsive: no http calls respond at all. Restarting the process keeps it alive for maybe an hour and then it hangs up again.
Thought it was caused by
JENKINS-13154 but we installed 1.510-SNAPSHOT and the box is still incredibly unstable. See attached threadDump from when the box was unresponsive. Looks like it's trying to load fingerprint data? I've temporarily moved our 228mb fingerprint dir and that seems to have helped quite a bit.
