Here is my situation.
I had an nfsd proces which was using up all the I/O the machine could 
handle. I could kill it, but another nfsd will again will just pickup the 

I am basically trying to tie up the process ID from ps/top to a particular 
machine connecting to that particular nfsd daemon.

So.. figure I start out in top, then "m" to view I/O, then 
o "total"  to sort.. 

I see an nfsd with let's say a process ID (PID) 419 doing hundreds 
of transactions per second.. and vmstat "b" column shows the HDs are falling 
behind with nearly 200 transactions pending.. I now want to find what 
machine is connected to the nfsd with PID 419

My guess is that a program was having problems and was doing lots of 
transactions... at the client.. problem is that I don't know which 
client machine.

I tried tcpdump, but that pretty much showed me all the nfs clients. :-(

Hope that clarifies what I am looking for.
