Any idea to remove the error?
Thanks in advance...

[gottfrois]

Really not sure what's going on here. What I do know is that ActionController::Live Is not very stable and is more of a hacky way to perform live stream.
The gem is probably missing a place where we need to make sure we re-connect to redis database when we use multiple thread.

HI, I have been working last 2 days in a similar problem, but in my case the events controller is envolved.

I have detected a problem related about the connection pool and the Action::Live disconnection from the dashing/events page

The problem is described in the following pull request #105

May it could be related
