Automount map entries that refer to multiple hosts in the mount location (replicated mount), the automount daemon probes a list of remote hosts for their proximity and NFS version. If hosts fail to respond, they are removed from the list. If no remote hosts reply at all, the list may become empty. Previously, the daemon did not check if the list was empty following the initial probe which would lead to a segmentation fault (by dereferencing a NULL pointer). This check has been added.
