My server has 32 cores and 128G of RAM.

The site keeps crashing and I'm seeing this error in the logs: scoreboard is full, not at MaxRequestWorkers.Increase ServerLimit.

Here is my current Apache config:

MaxKeepAliveRequests    400
KeepAliveTimeout        5
Timeout                 300

<IfModule mpm_event_module>
