We can't access WHM/cPanel and any Website under this.

I just execute this two command and found this "service cpanel status and "netstat -ln | grep 2087"

service cpanel status Output

cpsrvd (pid 3839) is running...
entropychat is stopped
stunnel is stopped
qrunner is stopped

netstat -ln | grep 2087 Output

tcp 0 0 0.0.0.0:2087 0.0.0.0:* LISTEN

You've not posted anything out of the ordinary that would indicate issues.
Help! Linux ate my RAM!

I just execute this two command and found this "service cpanel status and "netstat -ln | grep 2087"

Both, normal output.

Have you contacted your Hosting Provider? A server being down completely might need the assistance of the guys at the DC.

OK I understand the RAM thing.

I contacted them they asked me to execute those two command after showing to them they told me to get help from cPanel directly. They are saying they do not provide cPanel support.
We are using cloud server.

Hello,

You will have to monitor your server to find out the process which are using high memory on your server. You can monitor your server using top and ps aux command.

With the following command you will get top 20 process which are using high memory on your server

ps aux | awk '{print $2, $4, $11}' | sort -k2rn | head -n 20

We can't access WHM/cPanel and any Website under this.

Could you elaborate further on this issue? For instance, do you mean these services are loading slowly, or do you receive a specific error message when accessing them, or does the connection fail?

Thank you.

Anyway I just restart the server and it's now running just fine. No problem with access WHM/cPanel and websites.
But if there anything that can help me to prevent future issue please let me know.

Also I need an expert advice to get a good cloud base company that can help me to run 1000+ Wordpress websites smoothly.

Even my server now working well I want to share with you our current server process.
After running the command I get this now.

ps aux | awk '{print $2, $4, $11}' | sort -k2rn | head -n 20

Could you elaborate further on this issue? For instance, do you mean these services are loading slowly, or do you receive a specific error message when accessing them, or does the connection fail?

Thank you.

When we had that problem and we tried to access it's loading and loading like it will take a year to load nothing comes up just a blank page.
