Thanks ZhangHuangbin

Set my /etc/my.cnf to: max_connections=256

that will be enough for an average of 250/300 emails per day !

That error should be normal on weekends anyway !

Thanks for the tip !

The connection to MySQL server initialized by Amavisd timed out, because you have too few emails.

Please decrease (or add) value of "max_connections" in /etc/mysql/my.cnf like below:

[mysqld]
...
set-variable = max_connections=512

If the same issue happened again, please try decreasing it again.

Hi digitalbit,

What's your current issue?

Hi ZhangHuangbin!

What would be your advise to set this:

$max_servers = ?;
$max_requests = ?;

... for a mail server of 300 emails average a day ?

Thanks !

That's the problem, established MySQL connection timed out.

Try to add below lines in /etc/amavis/conf.d/50-users before the last line "1;", then restart Amavisd service:

$max_servers = 1;
$max_requests = 1;

Thanks for your help.

In fact, this server is actually sending 10 mails each day.

MySQL is very quiet ...

I'll adapt my config.

Christophe

Seems your MySQL server is under heavy load, wasn't it?

Also, do you have "$max_requests" setting in Amavisd config file (/etc/amavis/conf.d/*)?
Reference: http://www.ijs.si/software/amavisd/amav … x_requests

If your server is not under heavy load, it's better to keep default value of "$max_requests".

Hi,

I was checking my log where I saw this error:

Oct 12 15:04:31 mail amavis[22655]: (22655-02) NOTICE: reconnecting in response to: err=2006, HY000, DBD::mysql::st execute failed: MySQL server has gone away at (eval 115) line 166, line 176.

What does it mean? How can I correct it?

Thanks for your help.

Christophe
