Question

M. Kempe on Mon, 12 Nov 2012 12:04:14


While doing some performance tests while restarting Message Broker Service I got stuck with the following problem:

The test-queue shows around 200 messages in queue with a 'Size in bytes' of -96525 (negative).

The queue is still working and I can receive new incoming messages, but the 200 messages still remaining in the queue (I'm not sure it there are really 200 msgs in queue - but the namespace-manager says that!). I'm unable to receive till the queue count is 0. This happens every time when i'm restarting the Service Bus Message Broker during send an receive around 100 messages per minute.

Any help appreciated.

Thanks in advance - kind regards,

Micha

Hello Micha,

Are you using Service Bus for Windows Server RTM ?

Please reply with the output of the getQueueDescription call (NamespaceManager)

Hi Ziv,

I'm using Microsoft.ServiceBus.dll - Version 1.8.0.0.

The Microsoft.ServiceBus.MessageBroker.exe Version is 2.0.20922.0

The result of GetQueue is:

DefaultMessageTimeToLive  {00:02:00} System.TimeSpan
DuplicateDetectionHistoryTimeWindow {00:10:00} System.TimeSpan
EnableBatchedOperations   true bool
EnableDeadLetteringOnMessageExpiration false bool
ForwardTo    null string
IsAnonymousAccessible   false bool
LockDuration    {00:01:00} System.TimeSpan
MaxDeliveryCount   10 int
MaxSizeInMegabytes   8796093022207 long
MessageCount    610 long
Path     "System.String" string
RequiresDuplicateDetection  false bool
RequiresSession    false bool
SizeInBytes    -5460 long
Status     Active Microsoft.ServiceBus.Messaging.EntityStatus
SupportOrdering    true bool
UpdatedAt    {13.11.2012 07:14:49} System.DateTime

Hope it helps....

But, I can easily reproduce this error - so I can send you a sample of my project and you'll see the same problem perhaps ???

Cheers,

Micha

Hello

Does your scenario use de-dupe? Can you please send over the sample? Code snippets will do.

Hi Narasimhan,

I'd like to send my test project to you. But how???? eMail Address ?

Cheers, Micha

P.S. You mean duplicate detection? Requires Duplicate Detection: No!

Hello

Can you copy and paste the code snippets?

Too big to copy & paste. I'm using TransientFaultHandling & DynamicThrottling (taken from best practices of Clemens Vasters).... I'd like to show you the full test project....

Hi Narasimhan,

did you had the time for some investigation of my problem ?

Hi Micha

The issue is under investigation and we are trying to isolate the problem. Are you currently blocked from making further progress?

Cheers!

No - I'm just curious. Thanks.
