Negative Number of Messages In Queue

[Howard Sommerfeld]

Hi,

I am using RhinoQueues to monitor the number of messages my application sends up to the server.

When there is a backlog of messages, I send an email alert out.

I have noticed, however, that when there are no messages in the queue, the size of the queue is a negative integer. 

I get the size of the queue by calling the GetNumberOfMessages(string queueName) method from a singleton instance of the QueueManager class.

Has anyone experienced this, or can explain to me why the number of messages in the queue would at any time be negative?

Thank you,

Howard
