Server slow down issues - top command help look into

[fearmydesign]

Hi everyone! One of my servers has been running extremely slow today. I just ran the 'top' command to see where most process comsumption is coming from and this is what I noticed;

10% CPU Usage - php
16% CPU Usage - spamd
24% CPU Usage - Mailscanner
22% CPU Usage - rad1md2

I am sure a million things could be the cause, but based on what you see here, what would you recommend I start to look into? Thank you

I just looked under WHM / System Health / Process Manager - and I saw this at the top:

57% CPU Usage MailScanner: checking with SpamAssassin

This can't be good... but where do I go or how do I determine or stop what's causing this?

To see if the main issue is something with MailScanner, which is not a cPanel provided product, you could try disabling MailScanner to see if the server quits being latent. If it does, then I'd suggest contacting MailScanner about the issue:

::: Official Home Page for MailScanner - Anti-Virus and Anti-Spam Filter :::

They would know their own product best.
