[Backgroundrb-devel] backgroundrb launches concurrent instances of same job
Hi there,
Backgroundrb is working pretty well for me but I have a job that launches
two of the same job, apparently a minute(?) apart from each other.  Should
this be happening if I have repeat interval enabled with a job_key?  It
seems like it should wait until the job is finished before launching a new
instance.
--Backgroundrb_schedules.yml--
city_updater:
  :class: :city_updater_worker
  :job_key: :city_updater
  :worker_method: :do_work
  :worker_method_args: scheduled workers require some args, so here you
go...
  :trigger_args:
      :start: <%= Time.now + 5.seconds %>
      :repeat_interval: <%= 1.minutes %> 
It''s currently launching two instances of city_updater, one minute
apart fro
the other.
Hints or tips to avoid this appreciated!

[Backgroundrb-devel] backgroundrb launches concurrent instances of same job
A logger entry lets me know what action is being performed by the job.  The
job iterates through a loop and I see two different "loops" that being
worked on simultaneously.  The loop is a simple ruby loop:
category=Category.find(...)
Locations.each { |location|
	logger.info(''Category:''+category+'' CityUpdater:
starting city
''+city)
	...do work here...
}
It''s strange that it''s launching two instances.

you see these as processes or as log entries?
