Hi,

I reported an issue against ws (websockets/ws#1669) which actually can be traced back to NodeJS (851a691678 - #26363), introduced from 11.10.1 to 11.11.0.

Essentially there is some deflate'd data that cannot be uncompressed successfully. I hope it's okay to point to related issue for code samples and further discussion. If not please tell - I'll extend this report.
