Maximum MQTT msg payload with Websockets is limited to 64KB #216

Closed vogler75 closed 2 years ago

vogler75 commented 2 years ago

Version

Version 4.2.6

Context

I have tried to set the MaximumMessageSize to greater than 64k, but this does not work with Websockets. When I set it to greater than 64k, a client which sends a message bigger than 64k gets disconnected.

Do you have a reproducer?

https://github.com/vogler75/automation-gateway But it is not a simple one.

Steps to reproduce

  1. ... start Vertx based MQTT Server program with UseWebsockets(true) and SetMaxMessageSize(128*1024)
  2. ...connect MQTT client and publish a message with more than 64*1024 bytes
  3. ...client gets disconnected
