Network hangups on a 2100a

Every once in awhile, one of our 2100a machines running 4.0d will drop
off the network. It's very strange. The system can ping itself, but
nothing out on the net and nothing out on the net can ping it. This
usually happens during heavy network loads (like backups). Some
details:

        AlphaServer 2100a
        256mb RAM
        ~40gb disk space
        Primary job is NFS service
        100mb interface (/dev/tu0) Tulip card
        4.0d, unknown ECO level (how do I find this out???)
        NetBackup 3.1.5 client installed, Solaris 2.5.1 backup server

Right now we have a script that runs out of cron every 5 minutes and
pings a system on the outside that we know will be alive. It tries 4
times and then shoots itself in the head. Clearly, this is not the way
to handle this problem. But I'm the Sun and HP guy and I'm just
starting to pickup the Dec stuff so I'm baffled...

Any direction in solving this problem would be greatly appreciated.
Thanks!
