consumer timeout : undefined no longer works

### Describe the bug I have not test it in other patch version of 4.3.x tested with quorum queue and classic queue rabbitmq client for C# version is 6.8.x this config does not work in version 4.3.2, and I understand this setting is not recommended %% advanced.config [ {rabbit, [ {consumer_timeout, undefined} ]} ]. Client is giving these errors, ``` 6/24/2026 11:08:31 AM - ***ERROR - Unable to process message from queue. 6/24/2026 11:08:31 AM - ***ERROR - The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=541, text='INTERNAL_ERROR', classId=0, methodId=0 6/24/2026 11:08:31 AM - ***ERROR - RabbitMQ.Client 6/24/2026 11:08:31 AM - ***ERROR - at RabbitMQ.Client.Impl.SimpleBlockingRpcContinuation.GetReply(TimeSpan timeout) at RabbitMQ.Client.Impl.ModelBase.BasicConsume(String queue, Boolean autoAck, String consumerTag, Boolean noLocal, Boolean exclusive, IDictionary`2 arguments, IBasicConsumer consumer) at RabbitMQ.Client.Impl.AutorecoveringModel.BasicConsume(String queue, Boolean autoAck, String consumerTag, Boolean noLocal, Boolean exclusive, IDictionary`2 arguments, IBasicConsumer consumer) at RabbitMQ.Client.IModelExensions.BasicConsume(IModel model, String queue, Boolean autoAck, IBasicConsumer consumer) at DNVGL.Spi.QueueManager.RabbitQ.RabbitQueue.RegisterReceiver[T](IQueueReceiver receiver) ``` ### Reproduction steps 1. in advanced.config add this setting [ {rabbit, [ {consumer_timeout, undefined} ]} ]. 2.restart rabbitmq server 3. start rabbitmq Client service ... ### Expected behavior all consumers should be connected ### Additional context _No response_
