Rails - May 2008 - backgroundrb problem

I have this worker:

class ImportWorker < BackgrounDRb::MetaWorker
  set_worker_name :import_worker
  def create(args = nil)
  end
  def process(value)
    logger.info("Hello from process, value is " + value)
  end
end

When I try to start it and use a job_key I get an error in the
backgroundrb log file.

MiddleMan.worker(:import_worker,
''1'').process(''foobar'')

000000092  {
:  type: do_work: job_key" 1: worker_method:
process: worker: import_worker:  data" foobar
datafoobarjob_key1typedo_workworker_methodprocessworkerimport_worker
You have a nil object when you didn''t expect it!
The error occurred while evaluating nil.send_request
/Library/Ruby/Gems/1.8/gems/packet-0.1.5/lib/packet/packet_master.rb:44:in
`ask_worker''
/Users/andersw/Railsapps/tre-gui-prototype_import/vendor/plugins/backgroundrb/server/lib/master_worker.rb:104:in
`process_work''

If I don''t use job_key it seems to work.

Has anybody else seen this? I''m using backgroundrb from svn trunk and
rails 1.2.6 on Mac OSX.

Thanks in advance!

Abigail,

I often get this error when I do stuff like shut down and restart my
Backgroundrb server while Rails is running.  I have not conclusively
determined whether it matters if you start backgroundrb or the Rails
server first (don''t think it does), but if I stop both my Rails server
and backgroundrb, then restart them both, this error goes away.

I think it might also happen after you get an exception in
backgroundrb (especially in development mode), though that is
speculation, I haven''t gotten it in enough reproducible states to say
for sure.  What I can say is that if I stop and restart both my bdrb
and my rails server, the error goes away.
