I tried Autoscaler version from GitHub dated April 30, 2014 on Heroku, and got this error in monitor_middleware_adapter.rb:28

This issue happens when a long-running task in Sidekiq is being terminated with SIGTERM (which happens often when scaling down on Heroku using Linear strategy).

Here's a simple fix which worked for me.

Thanks for this fix. If you make a PR, I'll merge it.
