I have to admit that the status of the community version is not
exactly inspiring confidence. But thisis another topic...

I see this problem happening quite often. On average it happens about
twice per week, with about 30 jobs running per day. I think it is
worth noting that it is always exactly 2 jobs out of that batch which
fail, when are all started at the same time with the same priority.
But I cannot see anything special with these two configurations
compared to the rest.

In my case I had "VolumeRetention = 18d" for all volumes in this pool;
I have changed this now to 455h (= 18d + 23h). Let's see what
happens.
Thanks for the hint; I will report results in a while (either when it
happens again nevertheless, or in a few weeks when it is sure that
this helped).
Best regards,
Wolfgang Denk
