Issue with non transactional queue

[Pavlo Stolyar]

Given simple bus configuration

<bus threadCount="5" numberOfRetries="5" transactional="false" endpoint="msmq://localhost/my_endpoint" />

When queue was transactional, everyting was ok. But after changing of transactional attribute value to false, following errors appeared:

2012-11-21 09:49:57 [Rhino Service Bus Worker Thread #1] ERROR - Could not peek message from queue

System.Messaging.MessageQueueException (0x80004005): Operation was cancelled before it could be completed.

   at System.Messaging.MessageQueue.ReceiveCurrent(TimeSpan timeout, Int32 action, CursorHandle cursor, MessagePropertyFilter filter, MessageQueueTransaction internalTransaction, MessageQueueTransactionType transactionType)

   at System.Messaging.MessageQueue.Peek(TimeSpan timeout)

   at Rhino.ServiceBus.Msmq.AbstractMsmqListener.TryPeek(OpenedQueue queue, Message& message)

I don't have an idea what could be a reason of that errors. Maybe somebody have ideas? Thanks in advance
