SYMPTOMS

Consider the following scenario:
  • You create a receive location in Microsoft BizTalk Server. You set the character set property of the receive location to UCS-2 and UTF-16 or to UTF-8.

In this scenario, a memory leak occurs in a Dllhost.exe process that hosts the MQSAgent2 COM+ application. Additionally, the computer may respond slowly.
