[Dovecot] Panic: file mail-index-sync-ext.c: line 212 (sync_ext_reorder): assertion failed: (offset < (uint16_t)-1)

Hello, we are using dovecot v1.2.10 on debian stable (lenny) systems with mailboxes on NFS, and we are facing this quite ugly crash: 2010-04-27 10:59:06 IMAP(<mailbox>): Panic: file mail-index-sync-ext.c: line 212 (sync_ext_reorder): assertion failed: (offset < (uint16_t)-1) 2010-04-27 10:59:06 dovecot: Error: child 2429 (imap) killed with signal 6 (core dumps disabled) 2010-04-27 10:59:06 IMAP(<mailbox>): Error: Raw backtrace: imap [0x80f2ea1] -> imap [0x80f2f22] -> imap [0x80f2879] -> imap [0x80df6ad] -> imap(mail_index_sync_ext_intro+0x25b) [0x80e043b] -> imap(mail_index_sync_record+0x164) [0x80ce8e4] -> imap(mail_index_sync_map+0x2c3) [0x80cf6d3] -> imap(mail_index_map+0x465) [0x80c47f5] -> imap [0x80c1053] -> imap(mail_index_open+0x24f) [0x80c150f] -> imap(index_storage_mailbox_open+0x72) [0x80acbb2] -> imap(index_storage_mailbox_init+0x132) [0x80acf72] -> imap [0x80847f8] -> imap [0x8084a9d] -> imap(mailbox_open+0x69) [0x80b71b9] -> imap(cmd_select_full+0x1dd) [0x806503d] -> imap(cmd_select+0x19) [0x8065999] -> imap [0x8067c7c] -> imap [0x8067d19] -> imap(client_handle_input+0x2d) [0x8067e8d] -> imap(client_input+0x5f) [0x80687ef] -> imap(io_loop_handler_run+0xe0) [0x80fbc50] -> imap(io_loop_run+0x20) [0x80fb0c0] -> imap(main+0x5ea) [0x80712fa] -> /lib/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7dbf455] -> imap [0x8060361] the only solution we have found is to delete the dovecot.index* files, and let dovecot regenerate them at the next access. could you please give it a look?

[Dovecot] dovecot/deliver ... Can't open log file /var/log/dovecot/error.log: Permission denied
by Phil Howard 24 May '10

24 May '10

I'm getting this ... May 10 12:45:01 eth0 postfix/local[3416]: A788D685F7: to=< xxxxxxxx(a)xxxxxxxx.net>, relay=local, delay=13, delays=13/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure. Command output: Can't open log file /var/log/dovecot/error.log: Permission denied ) So I'm looking at http://wiki.dovecot.org/LDA to see what I can do about it. I would have hoped some comments in the example config file would have mentioned this and suggested a default practice solution. Is this something few people or many people encounter (among those using dovecot/deliver from Postfix)? If I do as the wiki describes and make separate log files for dovecot/deliver to use, do I just make them owned by Postfix? It would seem to me a different directory might be more helpful (absent log files could be created by having the directory permissions. I'm also thinking in terms of log rotations, too ... and I prefer to do log rotations by date stamping rather than pushing sequence numbers (the legacy log rotation). Any chance there are %-style variables I can use in log file/path names to make log files automatically named by the date (and maybe time) ... kind of like in a shell script I would do: `date +/path/to/tree/%Y/%m/%d.log` or such.

[Dovecot] Thunderbird very slow startup, 1.2.11, mbox, postfix local delivery to /var/mail
by Stan Hoeppner 22 May '10

22 May '10

I've Google'd to exhaustion and can't seem to find an answer to my problem. I'm not sure if the problem is TBird 3 or my Dovecot setup. The basic problem is that when I launch TBird and it grabs messages upon startup, it takes forever to supposedly pull them down. Once it's got them they sort relatively quickly into the proper IMAP (dovecot) folders. I don't use sieve yet; I sort with TBird rules. I don't sync messages for offline use. The only thing TB stores locally is the index cache, which I deleted and had TB rebuild once, which didn't help. All that did was waste more time, as I've got 40,000 messages in my IMAP folders which had to be re-indexed by TB. (I save all list mail for future searching). As an example of this problem, I'd not checked my email for just over day, had ~300 messages waiting in /var/mail/stan. TBird starts pulling them from dovecot and says in the status bar "downloading x of ~300". As I watch the count tick up +10 at a whack, the TB process is pegged at 100%, there is zero network activity, and the imap process on the server shows zero cpu use. It took over 60 seconds to "pull" the messages, after which TB sorted them. During the apparent sorting process, there is quite a bit of network activity and the imap process on the server is relatively busy. I say "pull" in quotes because the entire time TB is saying it's pulling more messages there is no network activity. The client and server are plugged into the same 100BaseT FDX switch (FDX verified), and the server has zero load. I know TBird isn't the greatest IMAP client around, but I think taking over 60 seconds just to download ~300 messages is way too damn long given the hardware resources, network, and load on the client and server machines. TB basically seems to be pulling, or dovecot serving, only about 5 messages/sec over 100Mb ethernet, which is abysmal performance given neither the server nor client have any load. The messages are mostly list mail which are at max a few kilobytes each. I'm leaning toward a problem with TBird but I've been unable to find a bug report that covers this, nor a forum post anywhere, etc. The closest I've found for "slow startup" are recommendations to compact folders. I have no local folders to compact. I delete immediately and expunge on exit. Anyone have any ideas? Other than switching to LDA+sieve and have TB check the IMAP folders for new mail? -- Stan

[Dovecot] Dovecot and /dev/shm
by DJ GRP 22 May '10

22 May '10

Hi, I have tried to use /dev/shm for Dovecot's index files: > mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/dev/shm/%u But it does not seem to like it. May 21 07:13:59 IMAP(user): Error: stat(/dev/shm/user/.imap/INBOX) failed: Permission denied (euid=1234(user) egid=500(group) missing +x perm: /dev/shm) It seems to me that /dev/shm permissions are OK. Any suggestions on how to achieve this?
