Fatal error link detached due to IdleTimerExpired

[lohmanndouglas]

Version:

github.com/amenzhinsky/iothub v0.7.0

Error:

Link detached, reason: *Error{Condition: amqp:link:detach-forced, Description: The link 'G2:...' is force detached. Code: ServerError. Details: AmqpEventHubConsumer.IdleTimerExpired: Idle timeout: 00:30:00.

I am getting this error message and restarting the pod Kubernetes container frequently. I had this code working for a long time and it did not happen so frequently. The first time, I thought that it was idle, but I checked the last message received was one minute before and not 30 minutes, maybe I misunderstand the Azure concept of idle in the Iothub bus and be observing the wrong parameters.

My contantainer log is:

... {"time":"2021-05-01T06:17:58.627919145Z", "message received"} {"time":"2021-05-01T06:17:58.633331806Z", "message received"} {"time":"2021-05-01T06:17:58.638524857Z", "message received"} {"time":"2021-05-01T06:18:02.227702684Z","level":"FATAL","prefix":"-","file":"main.go","line":"47","message":"link detached, reason: *Error{Condition: amqp:link:detach-forced, Description: The link 'G2:omited' is force detached. Code: ServerError. Details: AmqpEventHubConsumer.IdleTimerExpired: Idle timeout: 00:30:00.}

My golang code is:

parentCtx, _ := context.WithCancel(context.Background())
log.Fatal(iotHub.SubscribeEvents(parentCtx, func(msg *iotservice.Event) error {
	err = json.Unmarshal(msg.Payload, &identifier)
	log.Info(" identifier :", identifier)
	if err == nil {
                 HandleID(identifier)
	} else {
		log.Error("could not marshing identifier: ", err)
	}
       return nil
}

I am considering doing something like the following draft, but a little afraid of losing messages, now if there is an error I see due to the container reinitialization and fix it as soon as possible to do not lose messages.

draft:

for {
       err = iotHub.SubscribeEvents(parentCtx, HandleFuncHere)
       if err != nil {
	    if err == context.DeadlineExceeded { // IdleTimerExpired?
                     log.Errorf("iothub idle timeout")
	    } else {
		    log.Fatal(err) // another error
	    }
       }
	continue
}

This is a reasonable solution? Did someone experience something similar?

I appreciate any help that someone provides to workaround or understand better this issue, thanks :)
