Connection closes if fragmentation is attempted

[fabioberger]

I ran into the scenario where WS requests above 16KiB were causing the WS connection to close with code 1006 and reason Socket Error: read ECONNRESET.

If I set fragmentationThreshold to > 16KiB or set fragmentOutgoingMessages to false, the connection remains open and the request completes successfully.

This leads me to several questions:

Is this expected behavior? If not, what is causing it? What are the implications of disabling fragmentation? Is there some other upper threshold on the size of a fragment I should be aware of?

Environment: Node.js v11.15.0

Thanks in advance for any help!
