workers stall and no longer grab jobs
I've seen this repeatedly now:
Mar 01 22:36:52 openqaworker2 worker: [info] cleaning up 01515682-sle-12-SP3-Desktop-DVD-Updates-x86_64-Build20180301-1-qam-regression-message@64bit
Mar 01 22:36:52 openqaworker2 worker: Mojo::Reactor::Poll: I/O watcher failed: better don't do it twice at /usr/share/openqa/script/../lib/OpenQA/Worker/Jobs.pm line 159.
and then they don't act. But the worker is reported as online:
Websocket connection: Active
Seen: about a minute ago
But you can see it's not in: last job 11 hours ago.
