[rabbitmq-users] mqtt plugin keep alive

[Ankush Sachdeva]

I am using RabbitMQ MQTT plugin along with Paho Android client. I am trying
to implement a long running service, which tries to maintain a connection
with server at all times.
When I set my keepalive interval 5 minutes, the Paho client sends pings
every 5 mins but never gets a reply (and I receive no TCP packet on server
side). The TCP connection status on both client and server shows
established however.

This problem goes away when I set the keep alive interval less than 60secs.
Could someone please help me on what could be the possible reason for this?

What RabbitMQ version do you run? Heartbeats/keep-alive should work as you
expect.

+rabbitmq-users — please CC the list.

I am using version 3.5.1
Is there any way I can log ping requests to RabbitMQ? Firehose
doesn't seem to log that.

No. Wireshark should be able to help. We're happy to try reproducing things
on our end after we ship 3.5.2 (should be this or early next week).
