Hello!

I have a question. For the past 2 days I have been experiencing serious problems with my customers' websites being down because the HTTPD is going crazy or overloaded. I literally can't find anything in the logs where this comes from. If I restart the web server everything works again for a while.

We can't find anything in the Apache either. Only my colleague suspects that a script is boring, but they can't find anything at all.

My colleague has also increased the quota and everything has been updated to the latest version, but we now no longer know how to best solve this.

Unfortunately, increasing the quota has had no effect. Last night the websites were down again and with a restart of the HTTPD everything works again so far. Only we want to solve the problem for good.

We didn't adjust or do anything and it was spontaneous. Our other web server with the same versions have no problems.
 
You still need to check logs for requests, also what domain causes overloads, maybe mysql requests
 
Don't you use CSF or did you disable it sending your root server messages maybe?
Because most of the time if something like this is happening, CSF sends you a mail about the high load on the server.
When this happens, it also includes files like ps.txt with the processes and a link to apache server-status when you use apache.
Often you can see there what's happening too.
 
Thanks for your help!

We just notice that the HTTPD increases enormously and this causes the problem that the websites go down.

Here is a screenshot of the consumption. According to my colleague, we cannot increase this limit because it has been fixed. Or is it possible to give freedom in this?

you need to check not service monitor but Process Monitor (top), of after overload usually DA send you notification with all processes running and IPs connected. You can check this letter on admin level or on your email if you configured to send you copy of such notifications
 
I think, maybe when your website go down, apache will generate logs like this
scoreboard is full, not at MaxRequestWorkers.Increase ServerLimit." ? .

Next time, when go down, go check log in "/var/log/httpd/"
