Consider the following scenario:
- You install Cumulative Update 6 (CU6) for Microsoft BizTalk Server 2010 on a BizTalk server.
- You publish an orchestration as a web service that uses a two-way solicit-response WCF port (WCF custom binding).
- You configure the source of the incoming BizTalk message body to use Path with the following string in the WCF send port:
/*[local-name()='Fault']/*[local-name()='detail']/* | /*[not(local-name()='Fault')]
- Messages are sent to the web service at the same time by several orchestration instances.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
