High Load every day at 10:00 am
Hi, since 22 November, everyday at 10:00 the load of the server starts to increase until I have to reboot because it becomes unusable.
Since then, I'm monitoring everyday with this guide Troubleshooting high server loads on Linux servers and another tools that I use for my work. I've been working with WHM/Cpanel for almost 8 years.
Today, at 10:00 am I stopped mysql, apache, exim, etc... everything. No crontabs between 9:00 am and 11:00 am and the load starts increasing until I lost the server.
All processes are running with 0% cpu
I only see in /var/log/messages is that, everyday at same hour since 22 November.

Hello, You have to monitor your server using top command so that you will get exact idea which process causing the high load. Also, Please check if there any cron set for that time. 0 -
As i wrote in the first post, no crons, and all processes stopped. The output of the top when server was about to reach the limit and I rebooted it. The server is 4 CPU and 16 GB RAM, I rebooted when load was at 13 (1 min avg) Top (nothing is consuming that CPU) USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 19236 1164 ?

Install sar and start the service. It'll help you find what's driving up the load. Thanks! 0 -
I have sar installed and what I see from that is that this started on 22 November. No new account added on that week. As I said, everything is stopped and the server continues increasing its load. I never saw something like that. 0 -
Hello, You may also want to reach out to your provider to determine if there's any issues with the server hardware (e.g. failing hard drive). There's also a third-party thread here you may want to look into: Hard Drive health check Thank you. 0
