Fix CPU and RAM Overload in Xtream UI

Requirements:

Make sure pid_monitor is in crons.

Clean up streams_sys using stream tools
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.

Restart Xtream UI.

Fix Xtream UI Permissions
sudo chown -R xtreamcodes:xtreamcodes "/home/xtreamcodes/iptv_xtream_codes/" ;
sudo find "/home/xtreamcodes/iptv_xtream_codes/" -type d -print0 | xargs -0 chmod 755 ;
sudo find "/home/xtreamcodes/iptv_xtream_codes/" -type f -print0 | xargs -0 chmod 740;

sudo chmod 700 "/home/xtreamcodes/iptv_xtream_codes/config";

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, close the file and run the following command:

sudo sysctl -p

Reboot your server and check

after reboot, run these commands again to verify your changes:
```
ulimit -u
```
// should show 500000
```
sudo sysctl -p
```
// should show the above values
