fedmsg-hub wasn't running again on the MBS backend, so I restarted it. Can we set up monitoring, and/or automatic restart?

(Note it's called fedmsg-hub, but it's actually the internal UMB)

Find out as CS-2960 was reported. I restarted it by hand for now. 

Here's the log:

[root@mbs-backend asamalik]# journalctl -fu fedmsg-hub

Reason: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionLost'>: Connection to the other side was lost in a non-clean fashion: Connection lost.

Last time this happened was January 2025 (at least that's what my notes say). So it's not very frequent, but annoying nevertheless as builds are stuck in the build state and it's not obvious what's going on to the maintainer.
