Re: [Condor-users] Flocking drawback

["Thomas Materna" <materna@xxxxxxxxxxxxx>]

What do you mean by a mistake requirement? The job requirements is just
(Machine==machina1-in-poolA) || (Machine==machina2-in-poolA) || ...
It has no reason to start on a machine in pool B, and actually it doesn't
really start but the machines are claimed for a brief moment.
