Actually, upon instrumenting some code, it looks like RELEASE-4.4 gets it mostly right. It ejects a PROG_UNAVAIL call which causes the Solaris 8 client to back off. The correct message would seem to be PROC_UNAVAIL, but I would take PROG_UNAVAIL if I could get -current to eject it. The NFS server code is pretty tangled stuff. It builds RPC packets manually, switches uses from EPROGUNAVAIL as well as RPC_PROGUNAVAIL, has a jumble of macros with lots of side effects, and doesn't use anything from the RPC descriptions of NFS. I've been digging, but it has been really slow. It looks like it's probably some simple typo that got lost in the NFS megacommit. I've been trying to instrument the code to find the typo, but its taking a lot of effort. So far, I am seeing the packet getting built, but now I have to try to watch it on its way out. I must say that I now understand why no one is particularly enthused to fix these NFS bugs. Andy L.
