Title: /script/restart-web causing high CPU usage on CentOS 7
Post by: Spacedust on 2017-07-12, 23:20:38

It shows:

/usr/lib/systemd/systemd --switched-root --system --deserialize 21

with 99% CPU usage

and such simple restart takes about 10 minutes!

CentOS 7 using systemd instead sysv (aka initd) for service process. I have no idea how to customize systemd configs file like I do for initd.

Most issue for service restart related to php-fpm.

Under initd, need remove socket files (related to thread childrens) before restart for faster restart.

Maybe just run simple sh script. It works fast then.

Try update Kloxo-MR and run cleanup.

Updated. /script/cleanup now works so slow, that it takes almost an hour to complete with just a few domains :(

Your Server or VPS how much memory RAM has and which CPU has ?

It's a dedicated 8-core ATOM C2750  @ 2.40GHz + 8 GB DDR3 1333 MHz + 160 GB SSD

Was working super fast on CentOS 6.9.

I'm using the latest Kloxo-MR 7.0.0.c-2017071101

This is probably not the cause of Kloxo-MR, but CentOS 7 - this is causing:

/usr/lib/systemd/systemd --switched-root --system --deserialize 21

very high CPU load on almost every command so it's pointless to use such OS at this time.

I think I will switch back to CentOS 6.9 ;)

Switched back to CentOS 6.9 and everything is flying ;) CentOS 7 is ultra slow, so not recommended to anyone. Not worth the time. Better install CentOS 6.9 with latest kernel-ml.
