The Hotline says that the PROM upgrades for the DN10000 Ethernet card
are ready, and should correct all the TCP/IP problems (hesitations,
delays, nodes dropping of the net, nodes going comatose) - I will
believe that when I see it !!!
Apparently you have to contact your local support people to get the
PROMs ordered - WHY AREN'T THESE BEING SENT TO ALL SITES AUTOMATICALLY ???

We are also running SR10.3.0.6 on our DN10000, which is supposed to have
a software "patch" around the Ethernet problems - it may be helping
avoid the hangs (though we had one with the patch), but the
hesitations and delays are so bad that you have at best a 50% chance of
successfully doing a telnet/rlogin/ftp/rsh to/from the DN10000, and
sessions are constantly timing out.

P.S. Thanks for the posting about NFS 2.2; I would have already installed it
but I never received it for our DN10000 (someone at Apollo tells me it
is on the current software list though). We have enough TCP troubles without
that. I agree completely with the poster of that article -- "how does
stuff like that get out?" --- and I'll add "who beta-tested it and thought
that it worked"?
