Hello,

I've had a bot before but after updating the gem I've been seeing this error. I couldn't find any documentation/issue mentioning this. Any idea how to fix?

Do you see this right away? It looks like something is blocking the execution and eventually it runs out of worker threads.

This is just from running any sample? What's the easiest way to reproduce?

Also tested on a Centos 7 server with the same results, so it's not OSX specific.

I can reproduce.

This is specific to celluloid and is caused by the replacement of the Actor by a Thread in slack-ruby/slack-ruby-client#224. I am confused though to why this is happening, as the synchronous slack-ruby-client examples without the bot wrappers work fine.

That was done entirely to make specs happy, so I am going to try and undo this in slack-ruby/slack-ruby-client#228 and work around that problem.

Anyone care to try my branch?

Thanks @dblock, that looks to work perfectly now.

I released 0.13.2. I don't think we need to update the minimal version of slack-ruby-bot since it just affects celluloid. Everyone on this thread should bundle update slack-ruby-client.
