Yes, the many jobs in the queue is causing condor_q to time out. I have 
made some improvements in later OSGMM versions, but the issues has not 
been fully solved. Occasionally seeing this message is fine, but if you 
see it all the time, that is a problem.

Not currently. I have been thinking about putting an explanation in the 
classad so that that it could be seen with condor_grid_overview. Would 
you prefer that over have more information in the logs?
