Top Processes: Memory smtp 56.32%

Posted November 1, 2017 1.3k views

Hi Digital Ocean Community,

I’ve been monitoring my server over the last few days and i’ve noticed that the top process within memory is (constantly) smtp at 56.32% is this high or something I should be worried about? If so how would I go about debugging this? Im happy with terminal commands.

Server Running Ubuntu 16.04.3 x64 and has a small number of Wordpress sites running with serverpilot

Thanks for your help!

Thats odd!

Why don’t you check the mail server logs? (you might find the logs under /var/log/mail/*)
Plus, check the SMTP traffic via tcpdump in order to monitor the normal traffic flow. You may be under attack.
