Hi,

I'm using dict quota with mysql for track them via SQL query instead of read maildirsize file. Primary quota and enforcing is provided via userdb and is "maildir" type.

Since dovecot 2.1.10-13 (but perhaps even before) when a new user log in via POP/IMAP or receive an email for the first time dovecot created the entry for the users in the table "quota" of dovecot database with quota usage and number of messages (before of this login/delivery the user has no entry in the quota table of dovecot DB).

After the update to 2.1.14 when a new user login or receive an email for the first time dovecot was unable to create (immediately) the entry in quota table and in the log print these errors:

Feb 12 11:03:49 master: Info: Dovecot v2.1.15 starting up (core dumps disabled) Feb 12 11:04:02 auth-worker(31421): Info: mysql(localhost): Connected to database vpopmail Feb 12 11:04:02 pop3-login: Info: Login: user=<alessio@domain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=31422, secured, session=<eK4gJYTV1QB/AAAB> Feb 12 11:04:08 pop3(alessio@domain.com): Info: Disconnected: Logged out top=0/0, retr=0/0, del=0/9, size=18618 Feb 12 11:04:41 pop3-login: Info: Login: user=<alessio@domain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=31424, secured, session=<D7F0J4TV1gB/AAAB> Feb 12 11:05:11 pop3(alessio@domain.com): Info: Disconnected: Logged out top=0/0, retr=0/0, del=1/9, size=18618 Feb 12 11:05:11 dict: Info: mysql(10.10.3.19): Connected to database dovecot

[ here is when I "quit" from telnet session]

[ only now telnet close the session ]

This is the telnet session:

# telnet 0 110 Trying 0.0.0.0... Connected to 0. Escape character is '^]'. +OK Dovecot ready. user alessio@domain.com +OK pass ciao +OK Logged in. list +OK 8 messages: 1 1594 2 1594 3 1594 4 1594 5 1594 6 1594 7 3755 8 3714 . dele 8 +OK Marked to be deleted. quit

[ here dovecot wait about 3 minuts before close the connecctions ]

+OK Logging out, messages deleted. Connection closed by foreign host.

After 3 minutes of wait in the mysql database dovecot insert the entry for the new users:

mysql> use dovecot Database changed mysql> select * from quota where username='alessio@domain.com'; +--------------------------+---------+----------+ | username | bytes | messages | +--------------------------+---------+----------+ | alessio@domain.com | 2144030 | 15 | +--------------------------+---------+----------+

Errors like

Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Timeout after 30 seconds

were present also before the upgrade but they were occasional, now I had to disable "dict quota".

Can this be fixed?

My dovecot configuration:

fields { username = $user mailbox = $mailbox } }
