Hi,
Just to confirm this is still a major problem for me with the
2.2.33.1 release (did not exist in previous releases).

This appears to be breaking dsync at the moment and is caused by
something committed in the last week or so. This is with the
current
-git of dovecot-2.2 (eaf276b33).
The crash happens all the time - the logs are full of this
message.
