Re: [mosquitto-dev] Prefix disappearing from bridged topics after the first message

Seems like I accidentally cut the most important part from the log. I corrected the log below.

Emne: Prefix disappearing from bridged topics after the first message


Hi, I’m having a hard time understanding the following behaviour:


With the following bridge topic filter:


topic +/+/+/+/events out 1 /dev/ 15060012/dev/


...I publish a message to the local topic, using the following command:


$ mosquitto_pub -t /dev/serial/123/com_door/2/events -m "werwer" -q 1


...which in turn are correctly forwarded over the bridged topic: '15060012/dev/serial/123/com_door/2/events' to another message broker.


So far, so good. The problems start when publishing subsequent messages. Suddenly, the prefix has disappeared from the bridge (as can be observed from the included mosquitto log). These subsequent messages never reach the other server. When restarting the local mosquitto, the first message published after restart are forwarded.


I’m on Ubuntu 64-bit, using mosquitto version 1.4.1 (build date 2015-04-03 07:41:26+0000)
