I hear you, but see below.

Not so far. As far as I can tell, this happens every few days for
processes doing a fixed workload. If this happens due to a transient
network glitch, I reckon that it will be quite hard to reproduce
reliably.

I see your point. At least half of my question is answered by knowing
that you have not seen this before :-)

I will dig in further to figure out what exactly is going on and share
my findings (if any). If we can figure out what the problem is, we can
have more confidence that a newer version actually fixes it.

Thank you,
