Hello, I have an issue where amavis service stops for no reason.  I restart the service and all is fine, and then it stops.  Is it a memory issue?

Thanks, Greg

Yes, memory issue.

With iRedMail-0.8.7, Amavisd is configured to prefork 10 processes, it will take some memory. If you have very few memory, try to set it to 1 or 2. For example, in /etc/amavis/conf.d/50-user, find parameter '$max_servers' and set it to 1 (or 2), then restart Amavisd service.

$max_servers = 1;

NOTE: Make sure you don't have duplicate parameters in this file, the last one will be used.

Re: amavis service continually stopping

Oops, forgot to mention that you must update Postfix config file /etc/postfix/master.cf to match '$max_servers' setting in Amavisd.

# File: /etc/postfix/master.cf
smtp-amavis unix -  -   -   -   10  smtp
    ...

Here 10 should match the value of '$max_servers'in Amavisd config file. That means if you set '$max_servers = 2', you have to change '10' to 2 in master.cf.
