[Bug 1478190] [NEW] neutron.tests.functional.test_server.TestWsgiServer.test_restart_wsgi_on_sighup_multiple_workers failed with psutil._error.NoSuchProcess

 

Public bug reported:

The test failed in feature/qos at least once so far. We don't touch wsgi
code there, so I assume it's something from master.

As far as I see, nothing in any other logs that would help to understand
why the service died.
