[Dovecot] MySQL client out of memory error

[Alexander Shikoff]

Hi,

I'm using Dovecot 1.0-alpha5 as POP3 server with MySQL DB of users.
Sometimes clients get an authentication errors. In this time dovecot
writes to log file next lines:
Feb  7 11:14:30 orion dovecot: auth-worker(default): sql(user at mydomain.com.ua,192.168.3.36): Password query failed: MySQL client run out of memory
Feb  7 11:14:30 orion dovecot: auth-worker(default): sql(user at mydomain.com.ua,192.168.3.36): Password query failed: MySQL client run out of memory
Feb  7 11:14:33 orion dovecot: auth-worker(default): sql(user at mydomain.com.ua,192.168.3.36): Password query failed: MySQL client run out of memory
Feb  7 11:14:33 orion dovecot: auth-worker(default): sql(user at mydomain.com.ua,192.168.3.36): Password query failed: MySQL client run out of memory

Can anybody say is there a bug in dovecot or this this issue is 
mysql-specific problem? 

Thanks in advance, Alexander
