web server help needed

[dlewis23]

For what ever reason today at around 12pm est. my server started acting really funny, and come to find out the hardrive is constantly being accessed at 24mb/s, but the odd thing is that the cpu usage is real low never above 5% and the memory usage is only 40-50mb out of 512mb available. if i start killing processes, i have to kill them all before that will stop, but it doesnt matter what the last process is that i kill. Does anyone have any idea what may be causing this becuase i am out of things to try.

Do you use monitoring system with your dedicated server?

Do you use it to host others, if so check the accounts - bots,eggdrop,IRC,shoutcast......
