We are currently trying to find out a good Opcache size for our production server.
As I was reading the docs, I came across this sentence: "Never ever run out of shared memory space, if you do, you will lock your processes, we'll get back to that later."
Is that sentence still true? I just can't imagine, that it is. If it was, our processes would be constantly locking. Or maybe I am understanding him wrong. By "lock your processes" I am thinking of all processes being in the "waiting" state and no work get's done.
Can't we just raise the `opcache.memory_consumption` until all the moodle code fit's inside there?
