Major - P3 The Jenkins test machine detected a hang when running the reconfigure test. The hang was when shutting down the statistics log server, the reconfigure thread ends up waiting for the statistics logging thread to wake. The current wait time is 76,000 seconds, so it will wait essentially forever.
The relevant call stacks are:
