I just issued a command to hold all my jobs that were
not running. I used the example on page 426 of V_6.6.0 manual:
[rannou]$ condor_hold rannou -constraint Activity!=\"Busy\"
User rannou's job(s) held.
Couldn't find/hold all jobs matching constraint (Activity!="Busy")
What happened? All jobs that were running got killed!!
Thanks for your help
