[Maxwell Banks]

Server operating system version

CentOS Linux 7.9.2009 (Core)

Plesk version and microupdate number

18.0.52 Update #3

Hi, I have a Plesk 18.0.5.2 running on Centos 7 since 4 years without any problem...
But since last week, my web server is unstable ....
On all domains, I get a default Centos page for a few seconds and after the servers is fine and continues to work....
I can't find the error, but continue with the problem
Can I check some specific log to try to find any error?
In the plesk panel there is nothing strange, the usage in TOP is correct, the memory, cpu and disk space is ok....
If anyone has any idea, please thank you for your help.
