@] BR via Nginx :
Idea coming right out of the blue: have you given a thought on compiling
nginx (+ gradually modules) with valgrind? You should know pretty quickly
if something is wrong.
Thanks for this idea which can really improve the eng process...
Brotli seems the main suspected issue
Ano
Thanks for your feebacks. I do my best seriously to communicate what I can
!
We note this issue on very busy server only, it will be hard to remove all
modules on such busy server, and reconfig all, but not impossible. Anoop is
on the case on smallest servers, and succeed to see the issue at small
Thanks for info, Anoop will read this, he is subscribed

cpanel stat generation cause thet nginx makes a lot of reload to grab new
file descriptor... no issue on that
Issue is nginx, I show you situation now with 2.58% used for 1 work, which
is same value for others, but gloably, nginx uses now 2.58%, this number is
increasing slowly at the rythm of ngi
I let dev Anoop answer to you... he has a clue about the issue :

We described it properly when opening ticket, I reformulate :
Usually, 1 nginx worker process consumes 1.16-2% of RAM maximum on this
server, and it remain stable.
For some days after nginx upgrades, every overnight, during daily stat
generation process of cpanel which happens on overnight like se
Uprgraded to last nginx version :
memory still increase it seems

After upgrade and recompilation, issue is much less important, it increase
only by 0.17% for an antire stats processing cycle, but issue remain
unsolved

i suspect :

Hi,
We suspect an issue on cpanel server from last update nginx.
Every overnight, there is many nginx reloads due to stat generation process
:
We see an ever increasing memory use of ngixn worker process, usually it
says around 1-2%, we now see it cumulating without coming back to normal
each ov
Im now testing what said sys nginx :
worker_processes 1;
Try 1 first and the error is fixed you can increase it to 4 or 8

Maxim,
After 29 hours error re-appeared jus tonce, which is much less than before
I see a correlation on my monit system at this exact time :
apache traffic had a peak, which equals to a big download peak
I'm now thinking to nginx tweaks i have not done yet
I now enlarge
from 64m to
client_max_
Thank you for your feeback
We reverted now to 1.11.3 with no brotly, and geoip module, (this version
had caused no issue)
