Websockets fail on CentOS kernel 3.10.0-327.13.1.el7.x86_64 and newer

Rancher 1.x

I have been doing some extensive testing today and had observed odd behavior related to websockets failures. I have narrowed it down to the CentOS kernel version. Kernel 3.10.0-327.13.1.el7.x86_64 and newer results in the following examples of websockets errors.

Is anybody else seeing this behavior?
