Re: [condor-users] useless idle ?

Submitter ads are what the schedd send to the collector when it has jobs
to be matched. It sends one ad per user. You can query all the submitter
ads on the collector with "condor_status -submitter". Without a submitter
ad, the negotiator doesn't know your schedd has jobs that need matching.
Either your schedd isn't sending its submitter ad(s) in a timely manner or
they're not reaching the collector. The ads are sent via UDP, which can be
a problem on heavily-loaded networks. You can try using the
TCP_UPDATE_COLLECTORS config parameter to have the ads sent using TCP
