sounds a bit similar although I don't really see how it would apply here.
Would be a good idea to try anyway with v2.2.22.rc1 (which seems to be stable
enough that I'll make v2.2.22 release soon).

We had been running 2 replicating servers (Maildir format) using version
2.2.10 under CentOS 7 in production for quite some time. In this forum,
I reported a problem that I traced to a timing problem where unread
emails being moved to Trash would magically reappear in the INBOX. I
have since upgraded our production servers to 2.2.23. The new version
resolved the problem. The version upgrade also resolved the occasional,
but annoying, dsync maillog entries "Duplicate file entry at line
...".
So, I am a very happy camper and appreciate the feedback.
