similar to: Dovecot stops to work - anvil problem

Hello, I'm migrating a mail server from a centos 5 cluster architecture to a centos 6 cluster architecture. The new cluster involves faster machines then the old cluster, and a virtual machine. I use dovecot-2.0.9-5.el6.x86_64, while the old cluster uses dovecot-2.0.1-1_118.el5. Tha mail server uses mysql for the users database, and a local ldap for authentication. The storage is also much

Good morning, we have 2 Redhat Enterprise 5.7 machines, they are a cluster with some mail services in it (postfix and dovecot 2). The version of dovecot is dovecot-2.0.1-1_118.el5 (installed via rpm). >From last week we have this dovecot problem: suddenly dovecot doesn't accept any new connections, the dovecot.log file reports lines like these Mar 15 12:38:54 secchia dovecot: imap:

Since the changesets: http://hg.dovecot.org/dovecot-2.0/rev/9bec70f26637 http://hg.dovecot.org/dovecot-2.0/rev/75b48fa3aec4 there is another problem.

Hello, just upgraded one of my testing machine from dovecot 1.2.15 to 2.0.7. After some trouble with permissions now all seems working, but when I stop dovecot I have these errors in log: Nov 9 17:08:07 in dovecot: master: Warning: Killed with signal 15 (by pid=20362 uid=0 code=kill) Nov 9 17:08:07 in dovecot: pop3-login: Error: read(anvil) failed: EOF Nov 9 17:08:07 in dovecot: imap-login:

You need to configure stats service client limit and imap service client limit. Those are different services than imap-login service.

Hi, The Dovecot wiki states that Dovecot's master restarts all died processes, which is good for availability. But when I kill dovecot/auth (to simulate an error condition which happened on a machine), the authentication fails with: Nov 16 14:32:40 be dovecot: imap: Error: net_connect_unix(auth-master) failed: No such file or directory It seems -albeit it gets restarted- dovecot/auth

Hello, Today while looking at a different issue (one user couldn't retrieve mail; DNS issue) I set 'mail_debug=yes' then ran `dovecot reload` on our mail server. After running the reload, dovecot started complaning about permission issues with the dict file, and preceded to try to kill it's self. The self reload didn't seem to work, and since this is a production system,

Hi, Is there any way of making sure the anvil service, used to penalty login fails, is working ? I dont see anything on the logs regarding it neither have it configured. It's not on my configuration files, but it can be seen on a 'dovecot -a' dump. Should it be logging something ? Should i have enabled it somehow ? Thanks for the answers.

Hi, I can confirm that in the bad behavior, the 5 second delay occurs at each AUTH in our case. I think the configuration we have kill auth process at each end of AUTH (and fork a new one for next next AUTH). I think the "disable" flag is local to the process that is killed / respawned. A collegue of mine, Laurent Guerby, has found a workaround for us and it's findings seems

We recently switched over mail servers to one running dovecot and postfix on RedHat Enterprise 6. The mail store is NFS on a NetApp filer, the index files are on local disk. We have about 6000 total active users, though not all of them access the system at the same time. All goes well for a while, then we start seeing errors like this in the log: dovecot: imap-login: Error:

Hello, I was using dovecot 1.2.x via xinetd with a setup like http://wiki.dovecot.org/InetdInstall Since I upgraded to Debian Wheezy, shipping dovecot 2.x, it no longer works.
