The job lease duration controls the schedd reboot survival


you must 
1) make sure your execute machines will allow leasing
2) make sure your submitters include "job_lease_duration" in their
submit scripts

Are you sure both the above are happening...

(also note that if you are using the other 6.7 series functionality of
streaming output that this will prevent leasing from working)
