I dont know if the message was ever copy that many times. I dont know any way to tell.
I'm pretty sure the message has been copied that many times. Possibly related to some lazy-expunge bug.. You could check this manually by:
I was able to trigger the error message with following. a uid copy 726974 inbox_2
First you'll need to find "map_uid" of the message:
map_uid=
doveadm dump ~/mdbox/mailboxes/INBOX/dbox-Mails/|grep -A 10 uid=726974|grep -w map_uid|awk '{print $4}'Next you can check that the reference count for the message really is 32767:
The ref counter was 32767.
doveadm dump ~/mdbox/storage|grep -A 5 uid=$map_uid | grep -w ref
And finally check where that message has actually been copied to:
printf '#!/bin/sh\necho $1;doveadm dump $1 | grep "map_uid.*\\b$2\\$" | wc -l\n' > /tmp/find.sh find ~/mdbox -name dbox-Mails -exec /tmp/find.sh {} $map_uid \;
The message was copied to a secondary folder. The action match one of the client side filter rules.
I found 3k other messages with same problem. They all have delete flag.
I upgraded dovecot the night before. I seen plugin errors during upgrade, in the pass. Do you think client made multiple copies during plugin upgrade? I will turn on debug logging for next upgrade.
What else can I do, in order to track down the problem?
