In attempting to use a microvax running ultrix 2.X as a gateway into the 
internet, I have recently been getting lots of "No buffer space available"
messages.  At first I thought I was running out of mbuf's but this dosent
seem to be the case.  Does anyone know what I can bump in this ultrix version
to improve this case.  (It recently got worse once we started using LAT
to this system)
 netstat -m
