Condor is a distributed system, so sometimes one side isn't ready to go
when the other side is. In your case, submitting from the central manager
is probably the problem - there's no network delay involved, so the schedd
didn't get the network delay time it usually would to be ready to talk
to the central manager. That it scheduled jobs on the next negotiation
cycle means that everything is working as it should.
(The above is a simplification, btw)

This is NOT "really bad". It's normal.

It implies no such thing. The state through the schedd is complex, and
occasionally we do "needless" things. We probably write those messages
out to the logfile.
