Server load up and down like a yo-yo
I'm absolutely flabergasted with this issue.
One of my servers is experiencing some significant load issues, and I can't for the life of me figure out why. This box has been very reliable over the past year, in fact, experienced over 200 days uptime until I rebooted a week ago in an attempt to resolve the problem. No new accounts have been added to this server in the past 30 days, and from what I can tell, traffic overall has not increased (averaging about 80GB transfer per month). In addition, no new scripts have been uploaded to the server that would be causing the problem that I can tell.
Anyways, the server is a P4 2.0g, 512MB ram. Disk/swap is not an issue. Server will be performing fine at loads in the .30 to .50 range across the board, but several times a day will spike upwards of 2.5+ and 1.5+ across the board. I have captured one of those times here in TOP and attached. Websites definately experience slowdown/performance issues when this occurs. Normal number of processes for this box is 80-95. You can see on the attached there are over 150 processes running.
What I have done in an effort to fix the problem:
-Disabled all chat services and Interchange within WHM
-Rebooted
I'm stuck, and need some advise as to how to track down the root cause of the issue. Thanks.
