Re: [mosquitto-dev] Client receives PUBREC and MQTT disconnected
|
Connecting with cleansession=true solved the problem, but all offline
messages are lost.
Why is the client receiving a PUBREC that it doesn't know how to
handle? What is going wrong here?
Thanks

Have you tried connecting with cleansession=true to clean up the state
for that client id?

Here's what happened:
_mosquitto_handle_pubrec handles the received PUBREC, then
_mosquitto_message_out_update updates the message's out status, but
in this function mosq->out_messages is NULL, so MOSQ_ERR_NOT_FOUND is
returned, _mosquitto_loop_rc_handle handles the response code, since
it's an error, finally _mosquitto_socket_close(mosq) is called.

Hi,
I am having problem with a particular MQTT client ID. When a
client connects to Mosquitto using this ID, it immediately receives
a PUBREC from the broker and then MQTT get disconnected:
2015-11-10 20:35:21.827 mqtt-test[58102:737651] === MQTT connected===
2015-11-10 20:35:22.329 mqtt-test[58102:737651] mosquitto log :

2015-11-10 20:35:22.454 mqtt-test[58102:737651] === MQTT

Log on the broker side:
...

testhost mosquitto[4911]: Socket error on client
362f23d0-8906-11e5-99da-005056355a83, disconnecting.
...
The broker is mosquitto 1.3.5. The client uses libmosquitto in
mosquitto 1.4.4.
Any help is appreciated.
Regards,
Khitai
