Container stops silently on SBFSpot crash

I recently had SBFSpot crash:

log (in case there's anything interesting)

I'd normally expect the container to either crash/stop or just continue working, instead the script seems to stop, but does not crash, so it's "stuck" so it has to be restarted by hand.

I think the culprit is SBFspot getting stuck and not exiting

I've seen this happen too now, once. @cromefire's suspicion seems very probable to me.
