My problem was with rpc processes failing during an
upgrade from OS4.1 to OS4.1.2.

The answer was given by Casper Dik. He suggested -

The problem was due to the machine being a gateway,
and running 2 ifconfigs. I had added the second ifconfig
after the first one, in the default position given by the
rc.local that came with the upgrade.

I found that by moving the ifconfigs to the start of rc.local,
then the portmapper and subsequent rpc demons would work.
