Yup. I think this was exactly the problem. The startd claims were timing
out. 

I disabled submits and cleared out the errant cluster (it took upwards
of an hour for the schedd to remove the 4k job cluster). Brought it back
to a stable state and then resubmitted and everything was okay. I think
the user may have issued an rm and then immediately resubmitted from the
same spot. Never good.

Probably time to bite the bullet and move to 6.8.5.

We're running Linux for our central manager nodes. But I'm sure there
are a number of improvements we can take advantage of in 6.8.5.

Hey Todd! Are any of the submit or remove performance enhancements you
talked about at Condor Week going to get back ported in the 6.8.x
series? I'm tempted to move to 6.9.x just so large cluster removals
don't take a hour plus...

Thanks for the help Matt!
