SystemExit when sidekiq restarted

[dfguo]

We are seeing SystemExit error pretty much when we restarted our sidekiq. We didn't see it before with our previous exception vendor. What is this about? Here's the stacktrace:

SystemExitvendor/bundle/ruby/1.9.1/gems/sidekiq-2.17.0/lib/sidekiq/cli.rb:82
exit

Hi @dfguo,

How are you integrating with Bugsnag? I've not seen this happen before.

It might happen if you are listening for exceptions in an at_exit hook?

Please re-open if you can reproduce this.

I'm getting this in Resque Scheduler too:
