Running `bundle exec sidekiq` throws Celluloid::DeadTaskError: cannot resume a dead task

Question

I followed Sidekiq's easy setup instructions found here, but I could not get it to work.

Here's the stack trace. I have also started the redis server. Anyone know what I am missing here?

Answer 1

In case anyone stumbles on this again. Had the same error when trying out the falcon patch for ruby 1.9.3, resolved it by switching from 1.9.3-p0-falcon to ruby 1.9.3-p327.
