More detail would be good..
New server? Server all up to date? Directadmin all up to date? Did you check Logs and disk space? Is the firewall up? does it happen a certain times of day? Cron maybe.
Memory
Code:
free -h
Disk
Code:
df -h
HTOP show anything
Code:
htop

+1 I have the exact same issue. New installation of DirectAdmin on Centos 7. Ran 'yum update' it was now at latest release 7.7 and then started freeze after a few hours. Server not responsive but no high CPU load, plenty of disk space and plent of RAM. No access to any external ports. Had to use console to get back on. Restarts didn't work either. Not a good start so far with DirectAdmin :(

And what directadmin has to do with it?

Is it a VPS? Do you run OpenLiteSpeed installed?

Does it run CloudLinux? It really sounds like an OLS bug. Please try switching to any other webserver.

I have re-installed the VPS with Centos 8 and re-installed DirectAdmin and see how it progresses.

I can confirm that with Centos8 and DirectAdmin I have had no issues. Current uptime 36+ days
