Maximum number of simultaneous connection to RabbitMQ with MQTT and AUTH_HTTP as backend

[fliwa]

Hi everyone,

I was wondering if anyone have the same setup as I we are and what is your maximum connected client in one node. Also when I try to fire a 50K clients connecting to the server, I can see some tcp disconnection is already happening.

Results of "rabbitmqctl list_bindings" after connecting 50K connections shows = "100007 bindings". Does this mean I have 100K connections to rabbit?

Please help. Thanks.


Here is my setup:

<mqtt clients>----->rabbitmq+mqtt_adapter----->auth_http_backend.

Here is the result of "rabbitmqctl status"
