Hey folks. I am semi-new to WHM. We just moved away from a hosted provider and are running our own WHM server, and CPanel. We are running the server in a VMWare environment, and we recently installed VMWare tools on our server (CentOS). I have came to work every morning this week to find that my server is unresponsive. No websites coming up, and can't ssh to the server. After doing a hard reboot in VMware all is well. The server runs during the day fine, and seems to go down like clockwork every night around round 8pm. Neither /var/log/messages or /etc/httpd/logs/error_log seem to contain anything relevant. At 8pm at night, the logs just stop until the reboot. Any suggestions or leads on where I should look next?
Are you doing maybe backups at that time, or maybe you have some other cron jobs running at that time?
Also try installing some monitoring software, Munin will be the easiest to install on cPanel/WHM, and see what is going on.
Also you didn't posted are you alone on that server, or there are other VMs running on that server. If there are others, maybe there are I/O issues.

According to me there must be some script or process which is getting executed between night time also I would suggest you to check your load during night time if it is being unstable then you grab that process, you can use sar -q for details load logs with time.
Also ask your Vmware providers to have a look on server and make sure nothing going wrong from their end.

Hello 
Did you install VMWare tools on the same server where cPanel is installed, or do you mean you installed it on the VPS hardware node itself? It's not recommended to install cPanel on a VPS node itself. Instead, cPanel should be installed on the individual VPS.
Thank you.

As I know VMware tools are used for the guest machines on the ESXi node, I think what user have tried is installed cPanel on perticular VM only and then tried for installing VMware tools as mentioned in below URL :Hello

And as I know it is not possible to install cPanel and ESXi on same hardware node.
