Our instance of jenkins has been becoming unresponsive after it has been running for several hours. We are on Windows Server 2008 R2 with Jenkins 1.647 and Java 1.8.0_73-b02. The jenkins process is still running when this happens. If one attempts to access the web dashboard, the jenkins process remains at 0% CPU while the java process consumes 100% of one of the cores. A restart of the jenkins service fixes the issue, but this has become a daily annoyance. I've turned on all logging to see if I could determine the culprit and here's what the log shows as the last few entries.

I'll be happy to gather more information if instructions for doing so are provided.
