I can't seem to be able to reproduce it easily at least. Looking at the code changes, I do see now that there is one related change that may be wrong, or at least the commit message is wrong:https://github.com/dovecot/core/commit/aae93d3ea73004ba1883bbf91c9e40f613ffc... - although it shouldn't affect anything unless there are already some other errors. But maybe there's something I don't see right now. Can you try if the errors go away by reverting this change?
We are getting the same warnings on 2 separate test servers; one with local ZFS storage, the other one with NFS storage (single server, data not shared with any other servers). We are imapsync'ing a few hundred user accounts from the production server so there is a lot of emails transfer a day. The warnings occur at random times and with random users.
I reinstalled 2.3.21 from source (originally was using Dovecot repo packages) and tested by reverting that commit. The warnings continued.
Next I tried with Dovecot 2.3.20 and still got the same warnings after a while.

I will try with an even older version to continue testing...
