Topic: High Memory Usage

Hi Everyone.

My VPS (1 vcpu/2GB RAM) is triggering high memory usage (100%) errors for me about once or twice a day.

It's a low load mail server. I don't mind occasionally going in there restarting some services if that's what it takes.

My htop and netdata is attached.

How do I restart the process taking up the most memory: clamd

I've tried:

service clamd status
service clamd.d status
service clamav status
service clamavd status

They all say that the service doesn't exist.

Re: High Memory Usage

With 2GB memory, it's expected that clamav may take 100% CPU while scanning emails.
At least 4GB RAM is recommended for a low traffic mail server to satisfy ClamAV + SpamAssassin.
