On a server with 30GB of memory serving somewhat high-volume traffic.
For some reason recently Apache2 has started running threads with insane memory usage. 500MB-750MB per thread is not uncommon right now.
memory_limit = 128M (php7.0 default).
Apache prefork config is on defaults.
The result is that we're running with only ~1GB of free memory.
What am I missing?
We have Nginx proxying requests and it's processes are more like ~60MB per thread. Here is a screenshot of running
Any insight as to what could be driving this is appreciated!
