 Posted: Fri Jul 10, 2009 10:37 am Post subject: dovecot + vpopmail/mysql fails very often in authentication |
 |
|
Hi !
From some time I have some problems with the dovecot configured on some different servers ( even on 32 or 64bit arhitecturs, all with gentoo linux, with dovecot version 1.1.7-r1 ).
I had to give up on using courier-imap because of it's courier-authlib that doesn't have any vpopmail support, so I choosed dovecot as I have seen some good reviews about it.
But sometimes I see that dovecot doesn't want to authenticate anymore, and it shows in it's error log the following error:
| Code: | dovecot: Error: auth(default): vmysql: sql error[3]: MySQL client ran out of memory
dovecot: Error: auth(default): Out of memory (Needed 8160 bytes)
dovecot: Error: auth(default): vmysql: sql error[3]: MySQL client ran out of memory
dovecot: Error: auth(default): Out of memory (Needed 8160 bytes)
dovecot: Error: auth(default): vmysql: sql error[3]: MySQL client ran out of memory
dovecot: Error: auth(default): Out of memory (Needed 8160 bytes)
dovecot: Error: auth(default): vmysql: sql error[3]: MySQL client ran out of memory
dovecot: Error: auth(default): Out of memory (Needed 8160 bytes)
dovecot: Error: auth(default): vmysql: sql error[3]: MySQL client ran out of memory

After I restart dovecot, it works very well. But this it's very disturbing, and I don't know what values to adjust anymore on the dovecot.conf file, as you can see it below:
| Code: | # grep -Pv "^\s*#" /etc/dovecot/dovecot.conf

Can anyone had the same problem, or at least give me an advice of what to do ?
P.S.: I have found this error on and old post about an very old version of dovecot with mysql support, but they ( developers of dovecot ) already solved that: http://www.dovecot.org/list/dovecot/2005-December/010400.html

| I think a solution could be increasing auth_process_size in dovecot.conf but I'm not really sure. If somebody could confirm |

set:
login_process_size: 128
Created a script: (run it with cron once a day)
#! /bin/sh
/usr/bin/killall -q dovecot-auth |
