SYMPTOMS
A memory leak in the Db2serv.exe file may be observed, as monitored by Performance Monitor (PerfMon) or Task Manager, when you run a simple Visual Basic application that does the following:
- Opens a connection (leaves it open).
- Opens a command object.
- Runs 1000 iterations that consist of calling a Stored Procedure (SP) by using the DB2OLEDB driver.
- Closes the command object.
- When all iterations are done, it closes the connection object.
