      In February we update our Jenkins to version 1.540 with automatic update tool and were unable to start again. Manually we stepped back to version 1.539 we hold since. However since we are using version 1.539 we have serious problems of blocking of the web user interface. Initially the user interface stops to respond eventually once a day or every couple of days, and lasted about 30 or 40 minutes; but in recent weeks the frequency with which the web interface stops responding has increased dramatically; and the waiting time has become excessive, exceeding the hour or hour and a half of waiting time, and requiring in most cases force the shutdown and restart the service by hand. This situation seems awkward to hold up because the number of projects grows weekly and Jenkins have to manage it. And the number of developers using Jenkins (and web requests) also grows.

      The symptom is that when we asked any URL to Jenkins server, the browser waits forever for the reply. Answer that never receives. Curiously, the rest of the service is still running. Looking at the log output in real time still appear activity start and completion of tasks when changes are detected in the Subversion repository.

      Looking for similar issues recorded near the approximate date that we update Jenkins, I found https://issues.jenkins-ci.org/browse/JENKINS-21487 and https://issues.jenkins-ci.org/ browse/JENKINS-21487. However, in our case the service continues to run scheduled tasks. Just do not answer the web interface.

      Any idea what we can do?

      I also upload a dump of the threads that were running this morning after waiting half an hour for the web interface to respond. Finally we had to manually stop the Windows service and run it again.
