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 process. 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. :-( Anyone else with NFS servers have had to deal with a rogue client? In particular finding out which client it is. Running FreeBSD 6 Stable as of early january 06.
