Biztalk Server 2006 FIFO singleton orch MSMQ does not do his work …..

Hello,

I have a Singleton orchestration with one receive port and one send port

receiveport is MSMQ (private, serial and transactional)

Everything is correctly set as told in the Elementary FIFO Sequential Convoy Design Pattern in BTS2004

Everything builds, deploy ok.

Only one instance of the orchestr is created when receiving a MSMQ message but when messages arrived in the MSMQ in a bulk copy, only the first message is handle and i receive :::: 

The Messaging engine failed to process a message submitted by adapter:MSMQ Source URL:FORMATNAME:DIRECT=OS:HI-13277\PRIVATE$\BIZTALKQUEUE. Details:The published message could not be routed because no subscribers were found. This error occurs if the subscribing orchestration or send port has not been enlisted, or if some of the message properties necessary for subscription evaluation have not been promoted. Please use the Biztalk Administration console to troubleshoot this failure.

 for all the other messages in the queue

If another message comes in the msmq, it is correctly handle.

if messages are copied in bulk, only the first is handled … have tested with 100 messages

It works only if messages arrive one per one ..???? !!!

Wat is wrong …. MSMQ port is ordered and transactional, all scopes are synchronized, all ports are ordered. Two receive, one instantiate and create a correl, the other does not instantiate (in a loop) and follows the same correl  …. so ????

Any advices would be great.

Thanks
