Basic Pleskian
I have set the following parameters on the plesk subscription:
pm.max_children = 1
pm = ondemand
However the FPM process is starting 8 threads when the load is asking for it... this doesn't seem right.
The default is pm.max_children = 5 and that will spawn a lot more than 8 processes (about 25 from a quick count but I would assume it could spawn about 40 which is 5 * 8).
It is a server with 8 cores, but this puzzles me a bit... is each Apache thread possibly able to spawn a fpm thread?
Hope someone here can tell me what's going on and how to keep the fpm process count in check.
