When this happened to us the problem turned out to be that the
ethernet driver was reserving too many receive buffers.
Mike Karels suggested lowering NRCV.   (NRCV is in vaxif/if_qe.c.)
We dropped it from 25 to 15 on our systems and have had several
(busy) such gateways working fine since.
This has worked on both UCB 4.3 and Mt. Xinu.
