Many thanks to the net! My original question:

The answer is that we have a root process started by cron that deletes
any file in /tmp that's over 3 days old. In addition to deleting all the
legitimate files, this process was also removing the unix-domain socket
in /tmp/.NeWS-unix and /tmp/.X11-unix, thus causing new connections to
":0.0" or "unix:0.0" to stop working. To add to the confusion,
connections to "`hostname`:0.0" still work because the TCP socket is not
in the /tmp namespace.

Making the process overlook the sockets in question has fixed the problem.
