There seems to be a problem with portmap. After service portmap restart, does it actually get to the process table?? The service init script uses a program called pmap_set to load the previous known state of the portmapper. But if portmap fails for some reason, pmap_set will complain and you get the above error. So it could be a problem with /etc/rpc. You don't really need RPC unless you're running a network and using it for NFS.

The interface problem is related. ypcall and RPC all relate back to the portmapper. If the portmapper isn't working, none of its dependencies.
