Memory Leak in COMTI When Using User-Defined Types in User-Defined Types (324555)
The information in this article applies to:
- Microsoft Host Integration Server 2000
This article was previously published under Q324555 SYMPTOMS
If Microsoft COM Transaction Integrator (COMTI) is configured to use a "Customer Information Control System (CICS) or Information Management System (IMS) by using TCP/IP" Remote Environment (RE), and a client application repeatedly calls the COM+ component, which in turn instantiates COMTI objects by using user-defined types, eventually the application may fail, and then return the following error message:
"Method ~ of Object ~ failed"
NOTE: Other REs may exhibit the same problem.
If you use Microsoft Windows Performance Monitor to log data for the Private Bytes and Working Set of the Process object, a memory leak occurs.
CAUSE
The problem is caused by having Occurs Depending On (ODO) arrays in a user-defined type. Specifically, a call is made to obtain a VarDesc structure from a type library, and a free method call is never issued to release the memory back to the operating system.
RESOLUTION
To resolve this problem, obtain the latest service pack for Host Integration Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
