I'm running a server on heroku where I have intermittent channel layer 
communications between instances of asyncConsumers. Running heroku locally, 
I have no problem with redis channel connection since I can have as many of 
them as I want, but once I upload my server to heroku, it gives me a 20 
redis connection limit. If I use more than that my server errors out, so I 
try to lower the expiry time so inactive redis connections would close. 
BUT, if a redis connection expires and I try to use the channel name with 
self.channel_layer.send(), I'll get the error below, how do I recover from 
this error without having to have external calls to create another 
asyncConsumer instance?
