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 might fail and return the following error message:
Method %1 of Object %2 failed
Note
Other REs may exhibit the same problem.
If you use Microsoft Windows System Monitor to log data for the Private Bytes and Working Set of the Process object, a memory leak occurs.
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.
