Hello: Not sure if this is 1.0rc7 specific or not, but everything was working great until Dovecot died completely with this information in the log: Aug 21 14:44:16 sh01 dovecot: imap-login: Disconnected: rip=213.13.124.18, lip=67.59.79.11 Aug 21 14:44:16 sh01 dovecot: imap-login: Disconnected: rip=213.13.124.18, lip=67.59.79.4 Aug 21 14:44:16 sh01 dovecot: imap-login: Disconnected: rip=213.13.124.18, lip=67.59.79.17 Aug 21 14:44:17 sh01 dovecot: imap-login: Disconnected: rip=213.13.1...

Hi, After upgrading Dovecot from version 2.2.27 to 2.3.9.2, we are sporadically seeing lots of these errors in the error log on many of our servers: imap-login: Error: master(imap): net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailable The issue is causing significant delays and/or timeouts on login. From what I can tell, this happens because the imap-login service is unable to connect to the im...

Hi, Whenever my Dovecot installation is POP3-dictionary-attacked, a large number of log entries written to /var/log/local0 from the syslog showing all the POP3 login and shadow lookup failures is produced and then the entire Dovecot installation crashes, master and all. Unfortunately, it was running unattended under normal use, is apparently quite hard to reproduce (I wrote a Tcl script that just pipelined a load of random strings with user/pass but nothin...

I had our production systems running on rc23, however we ran into problems when the server was under heavy load. Eventually, the server would begin to freeze all imap connection after authentication (according to the logs). A user would connect, authentication would succeed, and then the connection would sit until timing out. No error logs were produced. Upgrading to rc24 did not

Hi, I'm still struggling with dovecot and Unixware: On my main server, I have two problems: 1- imap-login has great difficulties to connect to 'default'. I have traced it to accept in auth_master_listener.c witch fails with errno=71 (EPROTO) weird... 2- It some times works and I can log-in but imap gets killed by signal 6 (abort?)

I posted some questions a few months back and received lots of great help in getting my dovecot/postfix/LDAP setup working. Initially, I ran into the pipe failed too many open files error. I am running this setup on OpenBSD/sparc64 4.1-stable and so I put dovecot in its own class and upped the maxfiles setting for that class. This was back with dovecot 1.0 and everything worked fine. I

But if in the configuration of the director is stated login/director. Than I assume this socket should be in the login dir not?

While I not certain that this is related to the problem we are experiencing, we are also (more rarely) seeing these: dovecot: master: Warning: service(imap-login): process_limit (16) reached, client connections are being dropped imap-login was set to process_limit=16, client_limit=1250 (for a total of 20000 concurrent clients) on 2.2.27.

...nBSD 3.9 i386 machine (no time to upgrade yet). I downloaded the source from the dovecot site, compiled and installed without any problem. The server starts up find and runs for a while. After a few hours to a few days, the server stops sending the CAPABILITY statement when a client tries to login. I found a few descriptions of this problem on the web, but no satisfactory resolution. I added some debugging code to the functions in auth-client.c and got the following traces. Included in this email are a successful login attempt, a failed attempt, and a startup trace. I am not a UNIX s...

Timo, Just out of curiosity, how are incoming connections routed to login processes when run with: service imap-login { service_count = 0 } I've been playing with this on our test director, and the process connection counts look somewhat unbalanced. I'm wondering if there are any performance issues with having a single process handle so many connections. It seem...
