Karl Wright commented on CONNECTORS-590:
----------------------------------------
It looks like the long-running query was the result of a job coming to an end.
That, in turn, is because there are no active documents left for the job. The
job documents' docpriorities are all cleared, and then the job is put into the
inactive state:
{code}
// All the job's documents need to have their docpriority set to null, to
clear dead wood out of the docpriority index.
// See CONNECTORS-290.
// We do this BEFORE updating the job state.
jobQueue.clearDocPriorities(jobID);
IJobDescription jobDesc = jobs.load(jobID,true);
modifiedJobs.add(jobDesc);
jobs.finishStopJob(jobID,timestamp);
{code}
The finishStopJob() method is taking the job from shutting down to notification.
