ERROR o.s.i.m.i.MqttPahoMessageDrivenChannelAdapter - Lost connection: Connection lost; retrying...

Hello, we have encountered a problem, this problem will occur in our production environment, using version 5.5.9, but I can guarantee that the client id is unique, but the connection will be automatically restored soon, no reason has been found, we hope to use your experience to help us, thank your very much!

First of all we develop here a library of components and really don't experience with target production projects.
Secondly, it would be great to have some simple project from you to be able to reproduce on our side.
And third: 5.5.x is out of Open Source support since last week, so it would be great if you can upgrade your solution to the latest supported version of Spring Integration and let us know how it behaves.

I also encountered the same problem. May I ask if it has been resolved now? Thank you

We doubled the default values for the 'CompletionTimeout' and 'RecoveryInterval' properties, respectively. I did not find the core problem, but guessed that too many devices were causing the response to time out.

That's strange. The completionTimeout is already 30 seconds by default...
The reconnect must be handled by the client.
Apparently both of you are using very old, out of support, Spring Integration version.

Would be great if you share your experience after upgrading.

Thanks
