Trouble with high load average
I run dedicated server with several VPS at it. Last time I experience high load average value and high "wa" load. About 50 % I can see using "top" tool. It means that some process waits for input/output operations to be completed.
How can I investigate which process (PID) cause this "wa" value? It's difficult to check processes in each VPS and should take long time. Is there any tool or method for it?
Thanks.
