How To fix CPU and RAM overload on XtreamUI

tutorial

This solution is from the user @empire from XtreamUI Forum, all credits goes to him. I just successfully try this solution so I want to share it with you.

I hope this can support some of you as well it did for me – specially for VOD servers – Lets start

Make sure pid_monitor is in crons.

1. Clean up streams_sys using stream tools.
2. Optimize your server OS:

Set ulimit parameters on your ubuntu server. Check ulimit with this command:

Code:
ulimit -u

if it was 1024 then we need to increase it as follow

Code:
nano /etc/security/limits.conf

add the following lines to the end of your file:

* hard nofile 500000
* soft nofile 500000
root hard nofile 500000
root soft nofile 500000
* soft nproc 500000
* hard nproc 500000
root soft nproc 500000
root hard nproc 500000

Then save and close the file.

3. Optimize sysctl

Edit sysctl.conf – sysctl preload/configuration file (these settings has been taken from an LB that had xtream-codes installed to it)

Code:
nano /etc/sysctl.conf

add the following lines to the end of your file:

Then save and close the file.

run this command:

Code:
sudo sysctl -p

4. Reboot your server and check it now !

after reboot, run these commands again to verify your changes:

Code:
ulimit -u

-> should show 500000

Code:
sudo sysctl -p

-> should show the above values
