its filesystems so that other hosts can access them over the network
and mount them as if they were on local disks.  NFS is built on top of
the Sun Remote Procedure Call (RPC) framework.

A part of the NFS server code charged with handling incoming RPC
messages via TCP had an error which, when the server received a
message with a zero-length payload, would cause a NULL pointer
dereference which results in a kernel panic.  The kernel will only
process the RPC messages if a userland nfsd daemon is running.");
