[Condor-users] condor_submit_dag not spotting dependency bug

[Steffen Grunewald <steffen.grunewald@xxxxxxxxxx>]

Hi,

from one of our users I got the following report:

> I think I found a bug in condor (in the version installed on mauii).

... 6.7.3 for Alpha, running under Debian Sarge

Is this a known problem, and are there any plans to fix
condor_submit_dag? I agree that it might be a PEBKAC, but DAGs tend to
grow large and users would appreciate more assistance from Condor to
find such obvious dependency violations...

Cheers,
 Steffen
