Lite-On croaks under high load (0.90)

Thu Dec 3 15:22:25 1998

Below I've attached a message from one of our members who is trying to get
our new Beowulf up.  Apparently, he has things mostly working, but (we
have experienced this consistently to date) the driver for the Lite-Ons
(there are 2 in the master node) chokes if a high load is induced...he is
able to restart the networking and get it running again, but another load
spike kills it once again....this sounds driver-related...is it?  Any help
would be *greatly* appreciated.

Subject: status...

I've got it semi-working... arp tables, forwarding, etc.  Inner hosts can
ping outer hosts, and vice versa, through the master.  Unfortunately, the
master's networking still stops every once in a while, usually after a
period of high load (ie, flood ping, then try to telnet somewhere)  It can
be brought completely down and up again, including all routes + arps, and
restored to working.

I think its got to be a driver bug - Corbett, did you ever talk to Don or
the linux-tulip list?
