Hi, we're running dovecot 1.1.2 (centos5 32-bit rpm from atrpms) havn't had any real issues with it, but today it looks like an index has become badly corrupted. We're seeing this in the logs every time we log in to a particular account: 2008-09-10T11:56:07+01:00 mail8 dovecot: Panic: IMAP(xxx): Trying to allocate 2273345672 bytes 2008-09-10T11:56:07+01:00 mail8 dovecot: IMAP(xxx):

Hi guys, Anyone know what this error with deliver is (v1.1.1)? 2008-07-03T09:45:19+01:00 mail4 deliver(alexander): Panic: file mail-index-transaction.c: line 642 (mail_index_transaction_lookup): assertion failed: (seq >= t->first_new_seq && seq <= t->last_new_seq) Seen a few of these this morning.

Hi, About a week ago I upgraded our reasonably heavily loaded mail servers from a pretty recent courier version to dovecot-1.1rc10. IMAP performance on dovecot is amazing, however POP3 performance is worse than courier :-( I have uploaded some munin graphs taken today to http://linweb.atlas.pipex.net/dovecot/; the dovecot server is handling about 2000 pop logins/sec and 300 imap sessions (but

Dear All, I'm having an intermittent problem, with dovecot slowing to a crawl. Restarting dovecot fixes the problem. Looking at the maillog, I see loads of these errors.... dovecot: pipe() failed: Too many open files dovecot: Temporary failure in creating login processes, slowing down for now dovecot: Created login processes successfully, unstalling looking at the processes, I can see

My existing pop3/imap environment is courier imap + vpopmail + qmail with MySQL backend. I'm looking at migrating this to Dovecot. Currently I have multiple instances of Courier bound to different loopback IPs (the IPs correspond with the virtual IPs on a server load balancer). When a user authenticates they don't have to specify a domain - if they don't, Courier will use a

Hi there, I'm using dovecot 2.0.16 with a mysql user database. From time to time when we have a big influx of messages (perhaps more than 30 concurrent rcpt to:<> sessions at the same time so no auth-workers free?) or when we have a transient issue connecting to the database server, we see the message: Jan 25 16:38:23 mailbox dovecot: auth-worker: sql(foo at bar.com,1.2.3.4):

Hi there, I've been seeing this error in our logs quite frequently on our nfs storage (v3): 2008-11-10T13:24:26+00:00 mail8 dovecot: IMAP(XXX at YYY.com): nfs_flush_fcntl: fcntl(/var/spool/mail/XXX/Maildir/dovecot.index.cache, F_RDLCK) failed: No locks available Which is because we don't run lockd on our servers. Why is dovecot trying to use fcntl() ? I explicitly set it to use dotlocks

Following on from this thread: http://www.dovecot.org/list/dovecot/2010-September/052704.html <https://owa2010.webfusion.com/owa/redir.aspx?C=a447887e3d204944a8c766142df41453&URL=http%3a%2f%2fwww.dovecot.org%2flist%2fdovecot%2f2010-September%2f052704.html> in 2.0.16 I am seeing the same issues. I believe this would be related to some timeouts set on our mysql servers which are pretty

Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to

Hi there, I run a system that has a lot of virtual users. We invoke deliver from exim and pass the directory to deliver into using the HOME environment variable, so deliver doesn't do any database lookups during the delivery process. The exim pipe environment is described at http://exim.org/exim-html-current/doc/html/spec_html/index.html#toc0239, but basically I'd like to know the domain

Hi all, Lets say I have a maildir which doesn't contain any dovecot files but has some emails lying around in it. If I add a message to this mailbox using deliver, dovecot creates the uidlist file with a single entry (the message that was just delivered). When I then log in to the mailbox, all the other messages are added into the uidlist file in the normal order (directory list order I

Hi all, We updated to 1.1.7 a week or two back from 1.1.6 (both standard atrpms builds). Since doing so, twice now I've seen the imap services accept connections but they hang before the banner is printed (pop seems to be unaffected). I see this in the logs: Dec 23 14:02:15 mail9 dovecot: pipe() failed: Too many open files Dec 23 14:02:15 mail9 dovecot: Temporary failure in creating login
