It's 'amd' (am-utils) which is providing the incorrect responses. Trigger seems to be trying to access an automount on a host which is not running an NFS server. amd then sends back a garbled response over the loopback interface (after getting several "RPC - program not registered" responses). Whether this is causing our other problems remains to be seen.
