Dear Dovecot users,
I'm a sysadmin in a company that recently migrated the IMAP from courier-imap to dovecot :-) *urray*
Everything with the perl migrating scripts (version 1.0) went with OKs and it was a lot of fun (and pray) to move 400Gb of mails and migrate.. and everything is working even better :-)
The problem is for some outside users that use webmails, like:
- Squirrel
- Roundcube
- Horde
They claim that the connection is constantly dropping.. You might say now: "Webmail's fault!!!" as I said in the beginning :)
But the IMAP logs shows SEVERAL times (almost every 10mins ?!):
Apr 28 21:10:48 olive dovecot: IMAP(rcoelho): Maildir /cluster/mail/mailboxes/rcoelho sync: UID inserted in the middle of mailbox (192736 > 192720, file = msg.LDW0C) Apr 28 21:10:48 olive dovecot: IMAP(rcoelho): Disconnected: Mailbox is in inconsistent state, please relogin.
Apr 28 19:14:11 olive dovecot: IMAP(pcorreia): Maildir /cluster/mail/mailboxes/pcorreia sync: UID < next_uid (7874 < 7875, file = msg.5BNVC) Apr 28 19:14:12 olive dovecot: IMAP(pcorreia): Disconnected: Mailbox is in inconsistent state, please relogin.
and so on.
I read somewhere on the web that configuring the mbox_lazy_write=no should work .. it did not :-)
I have CentOS 5.4 in our mailserver, so the version of dovecot is not the latest (it is 1.0.7)..
But of course, this is production environment and I don't want to update if its not needed :-)
So my questions are:
- Is this a known bug for this version and I have to upgrade ?
- Is this a problem in my configs for dovecot ?
- Can this be other problem than dovecot ? -- so probably i should be able to add more debug anoying messages to our logs ?
- Probably something went wrong in the migration for these maildirs? So now what can we do to fix this ?
Our mail is working and, at the moment, I found 3 users with this error.. They have about 10Gb of mail each, I don't think this is a problem for dovecot.. only for our storages.. :-)
Tks for your patience, Best Regards!
