Could be a condor bug.  Looks like the schedd is detecting the situation

about it.  Interestingly, code to do something about it *used* to be
there, but is now commented out.

Restart the schedd. 

condor_restart -name <machine> -schedd

Make sure you're on a machine that has HOSTALLOW_ADMINISTRATOR privs.
