Ok, I did end up figuring this out!
I have Homarr on my network, and it had an OPNsense integration that was failing to request CPU stats data. Each request caused what I can only imagine is a new, long-lasting session, a new invocation of php-cgi from the configd python script, and subsequently just choked the system of resources to continue spawning php-cgi. Since this backs web requests, no matter the source, it was causing the failures.
I DOS'd my webgui. Lesson learned.
