So couple quick things first if you could submit a bug report via
bugzilla.
http://oss.sgi.com/bugzilla/
We have decided to give a bug tracking system a try.
Hopefully this will help with tracking and keep things from
falling through the cracks.
Second do you have any more info as to what is going on over the nfs
mount? it might help us reproduce the error locally.
