I am afraid I can't claim this test is fixed. I haven't checked why we
receive an
originating update on a deleted object
(this is the "Failed to apply records: (null): No such object" message
in the log).
I still suspect this is why we can't allocate RIDs in timely manner.

Yes, this is what I wanted to look into next. I hope I will have something in
next few days.

Thanks for you persistence in chasing those type of flaky tests!
