    • Jenkins 2.107.2
      Red Hat Enterprise Linux Server release 6.6 (Santiago) x86_64
      java version "1.8.0_51"
      Java(TM) SE Runtime Environment (build 1.8.0_51-b31)
      Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

      Since upgrading our Jenkins master from 2.89.2 to 2.107.2 (LTS) we have experienced the web interface becoming non-responsive (including jenkins-cli).  Restarting the service clears the issue, but it keeps reappearing.  SCM triggered builds appear to be continuing in the background.

      We did not experience this with the previous release.

      The stack trace reports a deadlock.

      Attached are the output from jinfo, jmap (heap), and jstack:

      • jstack -l <pid>
      • jmap -heap <pid>
      • jinfo <pid>
