On a cluster running Nautilus (14.2.8), we are getting a complaint about
a PG not being deep-scrubbed on time. Looking at the primary OSD's
logs, it looks like it tries to deep-scrub the PG every hour or so,
emits some complaints that I don't understand, but the deep scrub does
not finish (either with or without a scrub error).
Here is the PG from pg dump:

I've tried restarting all 3 OSDs in question, it didn't help. I'm
running the upmap balancer on this cluster (if that matters). Any ideas?
