Here is the stack trace which appears on resque-web interface: http://gist.github.com/396893
There you can check some gem versions that I was using.
Now I have made some upgrades trying to solve the problem, here are the current gem versions:
redis (2.0.3)
redis-namespace (0.5.0)
redisk (0.2.1)
resque (1.9.5)
resque-scheduler (1.9.2)
resque-status (0.1.4)
I have also wrote a very simple worker to discard any programming mistakes on my part, but also without any success. The test worker code is (though the bug occurs with any code using resque-status I have tried):
class SimpleStatusWorker < Resque::JobWithStatus
def perform
60.times do |i|
sleep 1
at(i,60,"At #{num} of #{total}")
end
end
end
(The appropriate initializer is being loaded in rails environment initialization).
