[QUERY] AmqpEventHubConsumer.IdleTimerExpired in Java EventHubConsumer SDK

Query/Question I am getting ERRORS of the type

The link 'G17:0000000:15_b00c67_1589608397028' is force detached. Code: ServerError. Details: AmqpEventHubConsumer.IdleTimerExpired: Idle timeout: 00:30:00.

• This ERROR is not thrown back to the application. Does this mean I am not supposed to handle it? Along with this, a few other ERRORS are also popping up.

I am unable to reproduce it on my own and the issue seems to be happening intermittently with no pattern (or atleast I haven’t been able to recognize it).

What am I supposed to do for these ERRORs?

Why is this not a Bug or a feature Request? Couldn’t reproduce it on my own.

Setup (please complete the following information if applicable):

• Version of the Library used: 5.1.0

@shubhambhattar The new version is expected to be released next week. I will update this issue when it’s released.

@shubhambhattar The error seems to happen when the network connection is lost temporarily and the receiver fails to recover even after the connection is restored. I have a PR open to fix this issue. https://github.com/Azure/azure-sdk-for-java/pull/11432
