Issue Sites go offline for no reason

Server operating system version

Ubuntu 22.04.5 LTS

Plesk version and microupdate number

Load is fine, only a couple sites on this new server and they keep going offline. Using Apache and there is nothing in the logs. Yes a couple pages have some errors but they shouldn't take all the sites down. The IP ban is disabled -- I see countless posts about same thing but no real answer, already tried adding the recommend code but no change
Starting to see why cPanel costs so much

Hello, @HiredHosting and welcome to the Plesk community. Unfortunately, the information provided is pretty generic in order for someone to provide you with a possible reason for the issue you are experiencing. If you can share some more details, such as what's the error/status your websites return when they appear offline; assuming that you are using some monitoring tool - what does the message you get indicate; have you checked your websites' log for possible hints; it could still help sharing the Apache logs. Basically, the more information you provide, the easier it will be for everyone to help you.

Yes I see the errors, I know one site has a lot of errors it's old and there are a lot it's going to take some time but one site shouldn't take down all the sites on the server.
Isn't that the point of PHP RPM? Ive had the same group of sites on the free Centos CWP panel and they never crashed. And the PLESK server doesn't crash either the resource usage stay low, the panel itself stays online along with all other services, only the sites don't load until I disable the problem and wait a few minutes. Enable and the net morning, sites are down.

And that search term "plesk all website go down" is a hot topic so it's not just me and I followed all the tips and answers but no change

I am assuming you are referring to PHP FPM. If that's the handler you are using and your websites are spawning lots of of processes it is very likely for you to be hitting the limits. You might take a look at the following article. On a side note, I would like to mention that it is a good practice to point out what sources you checked and what solutions you attempted to apply purely so we can avoid recommending solutions that you already tried, go in cercles, and waste your time.
