[Condor-users] Job that never runs due to constraint mismatch: where do default constraints come from?

[Rahul Nabar <rpnabar@xxxxxxxxx>]

I had a bunch of jobs that don't run on Condor but just wait in the
queue forever. Using "condor_q -better-analyze" I found the reason for
non-execution was a resource-request conflict. (see below for verbatim
output). Unfortunately I cannot figure where this "requirement" was
set up. My script was very minimal. I grepped in the codor users
directory but cannot see where those defaults were set either....Any
tips?

Also, is there a way to tell Condor to issue a warning if a job is
never going to be run. THese jobs stayed queued for a couple of days
before I figured out something was fishy. It is hard to say if a job
is just waiting for resources to be free or is in a deadlock that will
never resolve.
