Question Scoreboard full and/or max request workers limit

Hi All,

I am wondering if there is a max limit a domain can use so we can prevent that a single domain can bring down a server.

We are now seeing sometimes:

server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting
or
scoreboard is full, not at MaxRequestWorkers

The config is:

<IfModule mpm_event_module>
LoadModule cgid_module modules/mod_cgid.so
MaxRequestWorkers 2000
ServerLimit 100
</IfModule>

This is a 12 Core and 48GB server. And when you check the /server-status page its always 1 domain that fills up the entire scoreboard.
I like to find a way (if possible) to prevent that a single domain can bring down a server. We have already capped the max memory limit and cpu cores, but the problem is now moving towards the scoreboard.

So is there a option to say for example a domain is only able to use 200 out of that 2000 workers (10%).
Or how do others prevent that a single domain can bring down a server.

Kind regards,

Kevin
