Puma unresponsive when there is more than one ActionCable channel · Issue #25117 · rails/rails

Steps to reproduce I have made a repository detailing the issue here: https://github.com/robertlyall/puma_channel_problem If you checkout 879fde (one channel), and start the server - everything works wonderfully. Shutdown the server then checkout edc493 (two channels). After a number of page refreshes the request will hang. If you run netstat -atn | grep 3000 you'll see something like this: tcp4 1

actioncableはdevelopment だと１つしかchannel をはれない
