Service Bus Java client logs contain many WARN level error messages

We are running a Java client on a container in AKS, with Azure Service bus. And we are seeing a whole error sequence every seconds.
The functionality is working OK.
Is this valid normal flow?

We set the log level to WARN, to minimize the volume. It's taking up too much of our log storage.

log:

    Hi @Yaari, Yossi Thanks for reaching out. These warnings occurs when all links in the connection gets closed due to inactivity (idle) and new link has not been created in 5 minutes.

    These are all standard behaviors of the service, and you can avoid them by making send/receive calls on their Connection/Link which will automatically recreate connection/link.

    For more information please refer: https://learn.microsoft.com/bs-latn-ba/azure/service-bus-messaging/service-bus-amqp-troubleshoot

    let me know incase of further queries, I would be happy to assist you.
