A several lookup-domain.pl proceses eat all memory system, a lot of spamassassin process created too.
I can reproduce de error, when i try to make a backup of all virtual servers.
I click on make backup, and in a frist time all work normaly, but after a few minutes, several process of lookup-domain.pl apears and then several process of spamassasin... and the server crash.
I restart the server, and several process of lookup-domain.pl appears, but i killall all of them and the server working normaly.
This problem don't permit me to make backups, and I understand what's happen. I use virtualmin Pro 50
This is the top command when the server crash.
