Panic: file dsync-brain-mailbox.c: line 814 ...
Hi!
We have 2 servers replicating each other and after upgrade to 2.2.26.0 we are seeing this in the logs:
Primary server:

Secondary server:
Nov 17 09:37:40 secondarymailhost01 dovecot: dsync-local(user@domain.ee): Error: read(mailhost01.domeen.ee) failed: EOF (last sent=mailbox, last recv=mailbox_state)
I'm guessing that it happens during automatic full resync, but that's just guessing.
OS is Debian 8 (x86_64) and Dovecot is recompiled from Debian's unstable repository.

Looking at the logs more deeply we can see that it's pretty sure that it was automatic full resync causing this error. But if that's the case then replicator's status is giving wrong info.
It shows that full sync was successful and nothing failed - the process crashed and there were no more retries in the logs - how can it be successful?
