Unix VPS server going down at almost the same time every day
- by ronnz
My server load seems to be really spiking and many times the server goes down at the same time each night (Around midnight). I have about 20 cPanel accounts hosted on it and have tried everything I know to try to find what is causing the issue.
Some of the things I have tried:
Combined all site access logs found in /etc/httpd/domlogs and cannot see anything unusual at the time of server going down.
Checked most other logs in the var/log directory and found nothing indicating the issue at the time the server is going down.
Checked cron logs and cannot see anything unusual.. See below. Last night CPU spiked to 7.5 at 00:14.
What else can I be checking? How can I really monitor to find out the root cause?
