I can’t know definitively yet…I have to babysit my server and keep an eye on logs. But, I think I may have found the culprit for why I get timeout issues with #ActivityPub and #WordPress.

It might be PHP-FPM. If you’re using Nginx, this is kind of a “glue layer” for making PHP stuff talk to Nginx.

I host most things with Nginx, which sometimes requires configuring workarounds with traditional PHP applications. I was digging around in my logs during the latest server slowdown, and I got some error messages about pm.max_children and pm.start_servers being way too low.

Anyway, raising the amount seems to be helping? More word on this as experiments continue.
