I came in this morning to find my vanilla (2.9pl7) server in a very
strange state.  Clients can connect, however after that they just seem to
"hang" - never drawing the galactic, and having bogus numbers for stats
(107 ETemp, for example).  No matter what I do to the server, nothing
seems to reset it - killing and restarting the daemon, running
tools/setgalaxy, etc.  Nothing has changed in the . config files since I
initally set up the server, so I don't know what could have caused this.

Is there a way to "reset" the server without rebooting the machine?
