ruby 2.6.5p114 : CPU goes to 100% and connection stops without error

[urkishan]

I am using eventmachine and faye in my project and I am facing this issue the eventmachine and faye take 100% of CPU as I increases the CPU from 4 CPU to 8 CPU on AWS but still facing this issue.

I have also raised this issue on eventmachine, as I am not getting any response from them eventmachine/eventmachine#944

We recently released a new version of websocket-driver containing some optimisations that reduce the amount of allocation and copying done when it's parsing and serialising WebSocket frames. I don't know if this is the source of your problem but it would be worth upgrading to see if it makes a difference, as others have found it useful.
