The JobQueue does not claim a job until it tries to run that job, so
either it tried to run the other two and failed or they were put in
the jobqueue table with the hostname field already filled in.
Run your frontend and backend with "-v database" and see which case is
It sounds like it may be a settings issue, so check for duplicate entries
in your settings table for the JobsRunOnRecordHost and
where value in ( 'JobsRunOnRecordHost', 'JobQueueMaxSimultaneousJobs');
Both of those are global settings, so there should only be one row
for each setting and the hostname should be NULL on those rows.
