Ubuntu Version: 18.04.4 LTS
Mosquitto Version: Version 1.4.15
I have broker installed on Ubuntu.
The Broker and pub/sub works but suddenly the messages are no longer delivered. The only way to fix this is to restart Mosquitto broker service and then it starts working till the next time it stops.
I have one console instance where i execute
mosquitto_sub -v -u <user> -P <passwd> -t 'T/test' -d and I see the following
Client mosqsub|12363-x sending CONNECT
Client mosqsub|12363-x received CONNACK
Client mosqsub|12363-x sending SUBSCRIBE (Mid: 1, Topic: T/test, QoS: 0)
Client mosqsub|12363-x received SUBACK
In another console instance i execute
mosquitto_pub -u <user> -P <passwd> -t 'T/test' -m 'TEST' -d
Client mosqpub|12411-x sending CONNECT
Client mosqpub|12411-x received CONNACK
Client mosqpub|12411-x sending PUBLISH (d0, q0, r0, m1, 'T/test', ... (4 bytes))
Client mosqpub|12411-x sending DISCONNECT
But I dont see the message 'TEST' in first instance. After I stop Mosquitto broker and start again using systemctl then I re-execute mosquitto_sub and mosquitto_pub command , I messages start coming in.
The mosquitto log also doesn't provide any error clues.
Appreciate any help in this regard
