BUG: Mailbox renaming algorithm got into a potentially infinite loop, aborting
Hi all!
I have two dovecot servers with dsync replication over tcp.
Replication works fine except for one user.
# doveadm replicator status
username
priority fast sync full sync success sync failed
customer at example.com
none 00:00:33 07:03:23 03:22:31 y
If i run dsync manually, i get the following error message:
dsync-local(customer at example.com): Debug: brain M: -- Mailbox renamed,
restart sync --
dsync-local(customer at example.com): Error: BUG: Mailbox renaming algorithm
got into a potentially infinite loop, aborting
dsync-local(customer at example.com): Error: Mailbox INBOX.Foldername sync:
mailbox_rename failed: Invalid mailbox name 'Foldername-temp-1': Missing
namespace prefix 'INBOX.'
For more info see the attached sync_loop.log
Thanks for your help,
Alex

BUG: Mailbox renaming algorithm got into a potentially infinite loop, aborting
Hi all! I'm using Dovecot 2.2.36.4. Maybe someone can help, this bug makes the replication unusable for me.

BUG: Mailbox renaming algorithm got into a potentially infinite loop, aborting
You could try fix this by manually renaming the problematic folder. This is a bug though.

If it happens with you all the time, could you try: - Get a copy of both replica sides, e.g. under /tmp/replica1 and /tmp/replica2 - Make sure dsync still crashes with them, e.g. doveadm -o mail=maildir:/tmp/replica1 sync maildir:/tmp/replica2 - Delete all mails and dovecot.index* files (but not dovecot.mailbox.log) - Make sure dsync still crashes - Send me the replicas - they should no longer contain anything sensitive As for fixing, you could see if deleting dovecot.mailbox.log from both replicas happens to fix this. -------------- next part -------------- An HTML attachment was scrubbed...
