I am getting this error. I have deleted all logs from Activity/Jobs reports after finalize and delete, but still not able to see report:
"Waiting for queued job to start."
and I still get the usage error.
Check to see if there are scheduled searches on the search head that are consuming all of your resources. The Utilization Monitor for Splunk and S.o.S. Splunk on Splunk App are both good for this.

Is there a way to display/timechart # queued searches ?
Did you delete the your jobs from all application context?
