Cannot reach 30k concurrent connections

[dophlin]

Hi guys,
I experianced a weird behaviour of vernemq. I try to connect 30k clients with vernemq but when the number of clients reachs 28k they start to be disconnected. Is there any limitation or I am doing something wrong!?
I should mention that I did exactly the same test with mosquitto and there is not any problem with that and I can easily reach 60k concurrent connections.

Thanks

Hello,
this is most certainly configuration related.

In vernemq.conf, have a look at listener.max_connections and maybe max_client_id_size.
Look at erlang.max_ports.

What is ulimit -n in the shell when you started VerneMQ?

Other than that it's hard to tell without more information.
Feel free to send your vernemq.conf to info@vernemq.com, or ask on the public VerneMQ mailing list.
