Hi all,

I've been seeing the following problem for a while now (since
3.0-19981006-BETA) but was too busy at the time to report it or help
diagnose it further.  Now I've got some time on my hands...

I can fairly consistently wedge NFS writes to our server with the
following:

dd if=/dev/zero of=ick bs=8192 count=1000

which tries to write an 8MB file to our file server which is an Auspex.  I
have mounted Auspex from my 3.0-current machine (cvsupped and built this
morning) in NFSv3 mode.  This command will wedge one or more of the nfsiod
processes.  "ps -auwx | grep nfsiod" reports the following:

root     137  0.0  0.0   216   64  ??  I     9:12AM   0:02.31 nfsiod -n 4
root     138  0.0  0.0   216   64  ??  I     9:12AM   0:01.74 nfsiod -n 4
root     139  0.0  0.0   216   64  ??  D     9:12AM   0:00.27 nfsiod -n 4
root     140  0.0  0.0   216   64  ??  D     9:12AM   0:00.24 nfsiod -n 4

The two processes in state "D" are the wedged ones.  A separate machine
running -current from July 11 works fine.

Eventually all the nfsiod's get wedged and I'm forced to reboot.  NFS
reads work fine.

Is anyone else seeing similar behaviour?  What can I do to try to fine
tune a diagnosis and help solve the problem?

Thanks for your help,

Tom
