I=92ve made the change on two of my servers that have been exhibiting NFS r=
elated issues, so we=92ll see how this goes over the next couple of days, b=
ut am curious as to when one would use =91intr=92 in the first place, if by=
 using it, it could cause NFS to hang like this?  Granted, out of 11 server=
s using =91intr=92, this one server is the only one that I=92ve knowingly e=
xperienced the nfs_getpages, so it seems to be something hard to trigger =

Thanks
