Tutorial HowTo fix CPU and RAM overload on XtreamUI

[redhat]

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:

ulimit -u

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

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)

nano /etc/sysctl.conf

add the following lines to the end of your file:

net.core.somaxconn = 6815744
net.ipv4.route.flush=1
net.ipv4.tcp_no_metrics_save=1
net.ipv4.tcp_moderate_rcvbuf = 1
fs.file-max = 6815744
fs.aio-max-nr = 6815744
fs.nr_open = 6815744
net.ipv4.ip_local_port_range = 1024 65000
net.ipv4.tcp_sack = 1
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_rmem = 10000000 10000000 10000000
net.ipv4.tcp_wmem = 10000000 10000000 10000000
net.ipv4.tcp_mem = 10000000 10000000 10000000
net.core.rmem_max = 524287
net.core.wmem_max = 524287
net.core.rmem_default = 524287
net.core.wmem_default = 524287
net.core.optmem_max = 524287
net.core.netdev_max_backlog = 300000
net.ipv4.tcp_max_syn_backlog = 300000
net.netfilter.nf_conntrack_max=1215196608
net.ipv4.tcp_window_scaling = 1
vm.max_map_count = 655300
net.ipv4.tcp_max_tw_buckets = 1440000

Then save and close the file.

run this command:

sudo sysctl -p

4. Reboot your server and check it now !

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

ulimit -u

-> should show 500000

sudo sysctl -p

-> should show the above values

thx,
original XC installation have this lines config for user xtreamcodes in : /etc/security/limits.conf

Thx for share this info.

Anyone tested? It works?

Thx

Hello Guys

This setting is only for LB or also for Main?

 

[melk]

i used the command: ulimit -u
and it shows: 604168

do you think that i should use the commands that you said?
my limit will lower to 500000 as you said and not increase.

Very good it worked perfectly.

I don't need time I just asked a question, I remember that the rules attack the post and not the member lol.

Biggest problem with some members of this forum and the understanding of things.
We should design for good understanding for some.
