Found Nginx 1.19.0 stopped but no idea what happened

[evald ibrahimi]

hello everybody,

I'm using nginx 1.19.0 with ModSec on Centos 7. The other day it
happened twice that nginx was stopped. No idea what could cause the
issue but i found on the error.log the following:

So it seems the server was running out of memory and it stopped nginx?
Thank you
