You can then save those ads to files and try sending those ads through  condor_q -better-analyze  using the -jobads and -slotads arguments to pass the job and slot files.

almost like a Heisenbug, the problem seemingly disappeared after setting 
this and running condor_reconfig and probably for good when other nodes 
came online in this pool and the machine_count=5 job finally started.

darn, so, I'll add this to my "cheat book" and see if the problem 
happens again any time soon.

Thanks a lot!
