Alma 9 is so slowly in a period of time

Hi!

I have a server with alma 9 and from last 2 weeks is so slowly between 00:00 and 2:00 hours.

It has been working correctly from the last 8 month but now i have this problem, the main service affected is httpd.

In this server i have an app with php + mariadb and the configuration ha been the same from 3 years.

The server is updated and i have a firewall

The logs show no information that would help me determine what is going on

I will appreciate any help or comments

Perhaps a crypto miner virus?

Not really sure.

just a guess, any backup job scheduled or something else around that time?
