Greetings all,

If this has been problem/solution has been posted before, please disregard :)

I'm using NFS to serve out FLAR archives to Sun machines. These files are > 2GB, and the auto-installer for the Sun boxes mount the files, not the directories. mountd was refusing to authenticate these otherwise legit requests because the stat() call was bombing due the filesize being too large. I hacked up the quick diff below that fixed the problem. The files transfer correctly and completely, but I admit I haven't performed further testing.
