For some reason my load avg's will jump from 0.05 to 0.98 even to 1.50 when the cpu is only using 3%. I am thinking something is using the hard drive as I have load avg peaks of 6.0-7.0. I want to find out what is causing this as im curious to why they get so high. Does anyone know how to find out what running processes are using the harddrive or something like that?? Also how do I check if DMA mode is enabled, I know there is a hdparm in linux but I cant find anything like that for freebsd.. Thanks for you help Steve
