Thank you for your response but if this was an ongoing issue, I would have more
places to look and tools available. After rebooting the system, it just went
back to normal. The network team reviewed the load balancer and firewall logs.

Also a connection attaching to the load balancer, the servers are not directly
addressable, would have been routed to one of the other servers while Ap
You will need to do some more triaging. Suggestions for things to investigate
more deeply: http Log files, system log files, system performance monitoring,
connection statistics, source of traffic, TCP performance tuning, firewall
control, protection against DOS attacks... and that's just off
I don't think the TCP buffer would be clear if there was a continuing flow of
http requests during that time, whether the web server software was down, or
maxed out
But maybe I am wrong.

No PHP on the system at all. The web server was down for 15-20 minutes so
anything in the queue should have cleared, right?

Have you tried mod_status? That would clearly tell you which threads eat
resources for you.
You can share the mpm you are using ,the values you have configured for
then, also the list of modules you load, and the actual load you receive.
That alone can give great hints about a likely culprit.

Regarding the "load increasing quickly after restarting the daemons" ...
I do not believe just restarting the daemons clears the TCP queue. Nor does it
prevent new TCP requests. If it is an attack, then the load would ramp back up
immediately. That is why you have to reboot I am guessing.
