disconnect if keepalive is 10 #157

Closed bbigras closed 5 years ago

bbigras commented 5 years ago

Maybe related to https://github.com/AtherEnergy/rumqtt/issues/76.

This code often disconnects after 15 secs but not every time.

Thanks for the report. There is a major refactor happening now. I'll verify this as soon as I'm done with it

bestouff commented 5 years ago

FWIW I'm using 60s with VerneMQ as a broker, and I have frequent disconnections because rumqtt "forgets" to ping sometimes (I often see 120s between pings).

tekjar commented 5 years ago

@bestouff @bbigras Can you verify if develop branch solved this issue?

bbigras commented 5 years ago

I still have the problem. It still doesn't happen every time, only sometime.

Thanks for the report. This helped uncover a bug. I couldn't reproduce this with your example but some late publishes caused similar issue. I think the root problem is fixed and unit tests are in place. Want to give it a try? :)

bbigras commented 5 years ago

I don't seem able to reproduce the problem with branch=develop 5336f2d1126e10c807fe22263589f6e79ae95e82 :+1:

tekjar commented 5 years ago

Cool. I'll go ahead and close this. Feel free to reopen if this reoccurs

bestouff commented 5 years ago

Is there an official release where this bug is fixed ?

bestouff commented 4 years ago

Ping?

tekjar commented 4 years ago

Ah sorry. No release yet. I'll push to crates on monday

bestouff commented 4 years ago

Great thanks
