Sometimes on my application server 1 processor sows up fully busy in iowait state. Thus I think it is a single process causing the symptom. Can you help me how to identify it? --Trifo

I've used filemon when an I/O issue was occurring to locate an active file; this may direct you in finding the related process. Ethan Upvote 0 Downvote
