[Bug 503008] Re: Dovecot-auth doesn't close sockets
It's been 10 years since the last comment, however it appears from the historical discussion that the issue was resolved with a parameter added to a newer version of dovecot. All currently supported Ubuntu LTS versions have even newer versions of Dovecot, so presumably this issue is now long since fixed. If this issue, or a similar issue, is still a problem in more recent dovecot versions, please file a new bug report and we'll go from there. ** Changed in: dovecot (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/503008 Title: Dovecot-auth doesn't close sockets To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/503008/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I may be able to build a package for you from the Intrepid sources.

Would there be a reasonable way to add the archives for jaunty and rebuild the 1.2.9 version from the src package? -Gaylord Peter Matulis wrote: > Strange.

Strange. I built a Hardy virtual machine and 1.2.9 was installed. Indeed, the archives do say 1.0.10. I'll have to determine what happened with my VM. At any rate, if the error is thrown then that version doesn't support the parameter. -- Dovecot-auth doesn't close sockets https://bugs.launchpad.net/bugs/503008 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 503008] Re: Dovecot-auth doesn't close sockets
According to Chuck Short, the parameter should be in dovecot 1.1+, so I would not have thought the OS level would matter.

Weird. According to packages.ubuntu.com 1:1.0.10-1ubuntu5.2 is the latest for dovecot.

Hmmm, the default shipped with 8.10 is dovecot-imapd 1:1.1.4-0ubuntu1.3 but an updated 8.04 has dovecot-imapd 1:1.2.9-1ubuntu3 Why does this parameter work with the older version?

Re: [Bug 503008] Re: Dovecot-auth doesn't close sockets
Chuck, Sorry for the delay replying to this. I finally tried your suggestion, setting: auth_worker_max_request_count = 10 in dovecot.conf. I get the following on restart: * Restarting IMAP/POP3 mail server dovecot Error: Error in configuration file /etc/dovecot/dovecot.conf line 650: Unknown setting: worker_max_request_count Fatal: Invalid configuration in /etc/dovecot/dovecot.conf dpkg shows: ii dovecot-imapd 1:1.0.10-1ubuntu5.2 secure IMAP server that supports mbox and maildir mailboxes Any ideas? -Gaylord Chuck Short wrote: >>From http://wiki.dovecot.org/PasswordDatabase/PAM#head- > 71368e6eb385969ff27fcda066555b9c05822c09: > > Limiting the number of PAM lookups > > Dovecot v1.1+ or v1.0 with blocking=yes enabled uses auth worker > processes to do PAM lookups.

Chuck, sorry for the long turn around on this, but I've finally tried setting: auth_worker_max_request_count = 30 in /etc/dovecot/dovecot.conf.

I dont have a recommendation on the count, I guess you have to adjust it for your setup.

Re: [Bug 503008] Re: Dovecot-auth doesn't close sockets
so if I set auth_worker_max_request_count = 5 dovecot-auth will do 5 authorization lookup and exit, spawning a new dovecat-auth process?

>From http://wiki.dovecot.org/PasswordDatabase/PAM#head- 71368e6eb385969ff27fcda066555b9c05822c09: Limiting the number of PAM lookups Dovecot v1.1+ or v1.0 with blocking=yes enabled uses auth worker processes to do PAM lookups. Usually PAM is used to do only a single lookup in a process, so this may cause memory leaks in PAM plugins or maybe other problems. If you notice that PAM authentication stops working after some time, you can limit the number of lookups done by the auth worker process before it dies: # v1.1+: Set to non-zero to limit the number of lookups auth_worker_max_request_count = 0 Note that this applies to all lookups, not just PAM lookups. So for example if you've configured Dovecot to use both PAM and MySQL, both of the lookups are done in the same auth worker processes and both of them are counted as requests. ** Changed in: dovecot (Ubuntu) Status: Incomplete => Confirmed -- Dovecot-auth doesn't close sockets https://bugs.launchpad.net/bugs/503008 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
