There are a number of reasons a job could match but not make it to the startd. The ShadowLog or SchedLog may yield some clues.

Common problems include:

Firewall between schedd and startd
Condor permission problem on startd

Another unrelated problem that looks like this problem is

Job does actually start running under the startd, but exits immediately for some reason, and goes back to idle. Running condor_q periodically never catches it in the "R"unning state, so it looks like it doesn't match. The job log file shows what is going on in this case.
