This doesn't necessarily mean that the Sun NFS is correct, or bug-free, but just that Sun NFS has a bug-set that is compatible with (surprise!) Sun NFS. If you have another SCO system, try doing the same test with an SCO client & server. This may help to narrow the possibilities. Also, when you encounter this problem, does the entire network on the SCO box die, or just NFS? In other words, do telnet, ping, finger, etc still work? If so, it may just be a problem with SCO-NFS. If it crashing the entire network, including inetd, the problem may be in your TCP/IP software rather than the NFS server. Does nfsstat show any problems before or after the crash, such as lots of rpc badcalls? Good luck bug-hunting.
