[Dovecot] corruption and errors in dovecot-stable
Hi,
We switched from dovecot 0.99.something to 1.0-stable (on FreeBSD 4.10) a few days ago and have been seeing many errors and one corrupted mailbox so far. Almost everyone uses mbox format, and most users primarily use SquirrelMail; I use Apple Mail and Thunderbird, as well as accessing the mailboxes locally with Mutt, and have not noted any visible problems.
There have been several of these messages:
dovecot: Feb 21 11:40:06 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/trac (5308 > 1151) dovecot: Feb 21 22:57:13 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/trac (6458 > 1151) dovecot: Feb 22 08:37:03 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/reportlab-users (5162 > 3812)
Others:

(I think this refers to the mailbox that was corrupted)

I am currently reinstalling 0.99.14, but it would be nice to be able to switch to a 1.0-derived version again - we have to run two copies of 0.99.x to get what we want. If there is any additional testing I can do to help fix these problems, please let me know.
Thanks,

I do see the same errors.
Timo,
What about these errors in Dovecot-stable ? Are they bad or can we just ignore them ? I haven't seen any related fixes in the changelogs so I don't know if these are fixed or not.. Please tell us :)
Thanx !

dovecot-stable may handle mboxes a differently than 0.99.x, so I guess these could happen (although they shouldn't.. I'd like to know if this can be reproduced somehow?). In any case Dovecot should fix these and you shouldn't see these more than once per each mailbox. If they appear constantly for same mailboxes, there is a problem..

Probably somehow related to above error, but shouldn't happen.
dovecot: Feb 25 06:26:09 Error: IMAP(kbode): file istream-raw-mbox.c: line 383 (istream_raw_mbox_get_body_size): assertion failed: (rstream->body_offset != (uoff_t)-1)
Same here. Have to look at these.
dovecot: Feb 25 12:30:40 Error: IMAP(sachs): Transaction log file /home/sachs/Mail/.imap/INBOX/dovecot.index.log: invalid indexid (1109356120 != 1108933119)
Means the log file was recreated.
dovecot: Feb 25 12:30:40 Error: IMAP(sachs): Corrupted transaction log file /home/sachs/Mail/.imap/INBOX/dovecot.index.log: Extension record update update without intro prefix
Strange. Is dovecot running over NFS or something?
Can you reproduce any of these problems easily or do they occur only randomly?

Since I wrote this, I have upgraded to 1.0-test63; see my other mail for why I can't compile -test65 :-). I am only running this for my own mailbox, not for the other users on the system, who are back on 0.99.13.
dovecot: Mar 15 22:00:12 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/trac (14238 > 1151) [...] dovecot: Mar 16 13:02:45 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/trac (15539 > 1151) [...] dovecot: Mar 16 15:47:37 Error: IMAP(njr): mbox sync: UID inserted in the middle of mailbox /usr/home/njriley/mail/lists/trac (16855 > 1151)
so it looks like for at least one mailbox, it does recur.
The only other message I've been getting with 1.0-test63 has been:
dovecot: Mar 15 22:00:18 Error: IMAP(njr): Fixed index file /usr/home/njriley/mail/.imap/Deleted Messages/dovecot.index: recent_messages_count 1 -> 0 [...] dovecot: Mar 16 17:19:18 Error: IMAP(njr): Fixed index file /usr/home/njriley/mail/.imap/Deleted Messages/dovecot.index: recent_messages_count 2 -> 0

Strange. Is dovecot running over NFS or something?
No, mailboxes are on a local disk (FreeBSD 4.10 UFS).
Can you reproduce any of these problems easily or do they occur only randomly?
I am loath to expose the users to these failures, but I will try again to test for a short period with 1.0-test65 or later once I get it to compile.
