Description 
If the rpcbind process receives an indirect rpc call (in this particular case a call to the NIS service as a client tries to find NIS via RPC/UDP broadcast calls) it tries to find the coresponding local interface address.

If all available interfaces are "deprecated" the lookup function will fail and generate the following error message (LOG_ERR which is also send to the console):
Aug  9 13:10:00 hamlab120 rpcbind: netdir_merge failed for udp: n2a: hostname not found

The indirect call is then discarded.

An example of such a setup (all interfaces deprecated) is a non-global zone which got one interface assigned which is managed in the global zone via IPMP (thus causing the deprecated flag being set on the interface).
Work Around 
Don't use deprecated interfaces in non-global zones.

Ensure that the clients don't make any indirect calls (in this example of NIS clients the solution was to specify the NIS servers instead of using the broadcast mechanism on the client).
