In Microsoft Host Integration Server 2000, when you use the new Microsoft Component Object Model (COM) Transaction Integrator (COMTI) Context Array, a memory leak may occur in the Dllhost.exe process.
This problem occurs if multiple WriteContext function calls are made to the same COMTIContext keyword entry for a Context Array variable.

To work around this problem, use the ClearAllContext method or the DeleteContext method to delete the entry from the Context Array. Then, use the WriteContext function to write new entries.
The following Microsoft Visual Basic .NET code example demonstrates how to create the variables and how to use the DeleteContext and ClearAllContext methods.
