[Dovecot] Dovecot out of memory errors on Debian sid
by Ric 10 Dec '05

10 Dec '05

hi I have dovecot (1.0.alpha4-1) installed on a Debian sid amd64 machine (dovecot-imapd and dovecot-common). I am using this so that I can use both Mutt and something like Thunderbird to access my local Maildir folders. Sometimes it works fine. Sometimes when I try to access my mailboxes locally using Mutt, it hangs for a very long time (the bottom of the screen says "Selecting in..." (.in is the mailbox), and eventually gives me a blank mailbox with "(no mailbox)" at the bottom of the screen. In /var/log/mail.err I find lines like the following: Dec 3 06:39:02 localhost dovecot: child 4600 (imap) returned error 83 (Out of memory) Dec 3 06:44:03 localhost dovecot: imap(ric): pool_system_malloc(): Out of memory For example, it was working fine earlier this morning, but now I am unable to access the mailboxes and I'm getting the error messages in /var/log/mail.err. I have the same problem with Thunderbird; it hangs and cannot access the mailboxes. At my office I have dovecot (0.99.14-1) installed on a Debian sarge machine and it works fine. I would appreciate any suggestions as to what to try or what to look for. My dovecot.conf file is very simple: ## Dovecot 1.0 configuration file protocols = imap listen = localhost ssl_disable = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_extra_groups = mail protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } userdb prefetch { } user = root } Thanks, Ric

[Dovecot] "Out of memory" error in 1.0alpha3
by Sergey A. Lipnevich 10 Dec '05

10 Dec '05

Hi All, I have Dovecot 1.0 Alpha3 running on x86_64 Linux 2.6 multi-CPU box using Maildir folders. Moving messages from one folder to another in Thunderbird 1.0.7, regardless of their size (usually small), produced error 83, "Out of memory", when both of these parameters were unset (default): mail_read_mmaped, mmap_disable. The log line before the error was pool_system_malloc(): Out of memory. I initially changed mmap_disable to "yes", the error stopped, but it still wasn't moving messages reliably. I then set MM parameters more aggressively: mail_read_mmaped = yes, mmap_disable = no (and the third of the series, mmap_no_write, is left unset). The error stopped popping up, and the moving works speedily. Maybe the default for mail_read_mmaped should be "yes?" Thank you! Sergey.

[Dovecot] yet another update of the Dovecot AUTH patch: 20051208
by /dev/rob0 09 Dec '05

09 Dec '05

Wietse won't sit still ... removal of the lmtp(8) client broke the previous issue of the revised Dovecot AUTH patch. So I just redid it for the 20051208 snapshot: http://www.nodns4.us/postfix-2.3-20051208-dovecot-auth.patch.gz $ md5sum *gz ; ls -l $_ 32946afa424b3fbc04c8d9822e711e1f postfix-2.3-20051208-dovecot.patch.gz -rw-r--r-- 1 rob0 console 7287 2005-12-09 17:09 postfix-2.3-20051208-dovecot.patch.gz The original patch is here: http://dovecot.org/patches/postfix/postfix-2.2.1-dovecot-auth.patch Instructions are here (and don't forget the Postfix SASL_README too): http://dovecot.org/patches/postfix/README NB: Although my own postfix-2.3-20051208 snapshot compiled with the patch and is running, it is not tested at all. I'll try with AUTH later and see if it's working. I will not be able to test with LMTP. IIUC how this patch affects LMTP, it's only in that the USE_SASL_AUTH flag was changed to USE_SASL_CLIENT_AUTH. So the only people affected would be ones who are using Cyrus-SASL for client AUTH. Please let me know via either list (or offlist, see .sig) if you use this and have any problems. -- mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header

Hello, is dotlock supposed to work with NFS? I noticed that the default-locking method causes problems even with nfslockd started. Regards Marten

[Dovecot] Dovecot auth patch updated for Postfix 2.3-20051121
by /dev/rob0 09 Dec '05

09 Dec '05

Once again I have updated Timo's auth patch for Postfix 2.2.1 to work with a 2.3 snapshot. It applied cleanly and compiled and is running for me, but is not really tested. This is Timo's code, not mine. All I did was manually edit in the rejects from the old patch. Find it here if you're interested: http://www.nodns4.us/postfix-2.3-20051121-dovecot-auth.patch.gz md5sum: 6f01782a118f5407f1ed40f4714504cd postfix-2.3-20051121-dovecot-auth.patch.gz The original patch is here: http://dovecot.org/patches/postfix/postfix-2.2.1-dovecot-auth.patch -- mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header

[Dovecot] Controlling Dovecot with Webmin
by Lee MSN 08 Dec '05

08 Dec '05

Dear Sir I have just setup a Fedora 4SE server, with Webmin - latest production release and Dovecot .99.14. The only way to start dovecot is to be logged into the server as root - locally or ssh, and type the dovecot command. >From Webmin - logged in as ROOT, when I attempt to start Dovecot it tells me that it can't because it can not open the config file - permission denied. This indicates to me that Webmin is not really logged in a "root" but that doesn't seem right since I use root/password when I access the server per the Webmin instructions. Also, in the Webmin configuration for that server - it references a master.pid file. Which did not exist. I tried to create a pid file using the PID (19638) of the Dovecot service. That did not help the start up problem, but I am sure needs to be fixed before I can have the service start on boot up?? I got the PID number after starting Dovecot and then going and seeing the services that where then running. The user/group Dovecot where created during the install. Sendmail is running along with SpamAssassign. When I start Dovecot, logged in as root at shell, everything runs well, email is processed all the way through. Do you know how to resolve this problem of controlling Dovecot through Webmin and making sure the Dovecot will start on reboot of the server. Thank you very much. Lee D. I am new to setting up linux servers like this. _________________________________________________________________ Express yourself instantly with MSN Messenger!

[Dovecot] Dovecot login hangs often
by P P Anwar 08 Dec '05

08 Dec '05

Hi - We have dovecot version : 0.99.11 release : 2.EL4.1 on Centos 4.2, with an LDAP backend (Samba PDC) and pam set to authenticate against LDAP. Dovecot is set to use pam for authentication. It uses mbox, and the machine has very little load (95% idle, no memory pressure). Every 36 hours or so, no users are able to login to imap (we have only imap enabled). Other services that use the same backend are working fine (like squid and ssh logins) even while this is happening. So we are not sure if we can blame this on pam/ldap problems. When this happens, we tried a "service dovecot restart", and that results in saying the "address is in use". About 10 "imap-login" processes seem to lurk around holding on to the imap port. We can get dovecot service to start again, only after a "killall -9 imap-login". What kind of debug should we enable so that you all can diagnose this further ? Any other configuration things that we should try ? We prefer to stay with Redhat/Centos releases, but if this is already reportedly fixed in one of the later builds, we are open to trying one. Regards, Anwar.
