Hi,

I found this notices in my mail.log:

Jan 19 06:25:21 mailsrv01 amavis[12282]: (12282-08) NOTICE: reconnecting in response to: err=2006, HY000, DBD::mysql::st execute failed: MySQL server has gone away at (eval 100) line 166, <GEN32> line 694.

I already modifyed my amavis config (user-50.conf) and added the suggested $max_servers = 1; and $max_requests = 1; lines.
( http://www.iredmail.org/forum/topic2536 … ailed.html )
Which didn't help.

Currently my /etc/mysql/my.cnf max_connections=300

At the moment this server isn't do much, but it will serv 2000-3000 mails/day, what is your suggestion for this amount of mails?

Thanks, Robert
