Today on my backup MX I see this in de maillog:
amavis[920]: (00920-02) NOTICE: reconnecting in response to: err=2006, HY000, DBD::mysql::st execute failed: MySQL server has gone away at (eval 101) line 172.

I already searched the forum and found this topic:
http://www.iredmail.org/forum/topic2536 … ailed.html

But:
1. it seems configuration is different nowadays, as there is no 50-users file. Only amavisd.conf I see in this file twice:
$max_servers = 2;            # num of pre-forked children (2..30 is common), -m
and at the end:
# Num of pre-forked children.
# WARNING: it must match (equal to or larger than) the number set in
# /etc/postfix/master.cf "maxproc" column for the 'smtp-amavis' service.
$max_servers = 10;

1;  # insure a defined return

What to do?  O and $max_requests = 1; is not in the file.

2. Should I also set the max connections in my.cfg? Or is this for something else?
