sending this again with shorter logs. Restarting the backend was
successful, but I'd be curious to know if there's something i can do to
avoid it crashing again in future.

I woke up this morning and my frontends would not connect. There are lots
of errors in the log, but I'm not sure which ones are the problem, versus
symptoms of the problem.
