APPLIES TO


 * Microsoft .NET Framework 3.0
 * Windows Communication Foundation

SYMPTOMS
You use the COM+ Service Model Configuration command-line tool (Comsvcconfig.exe) to expose COM+ components in a COM+ application as Windows Communication Foundation (WCF) services. However, the COM+ application cannot start. This problem is likely to occur if one or both of the following conditions are true:
 * The COM+ application contains too many COM+ components.
 * The computer has limited resources, or the computer is under heavy load.



CAUSE
This problem occurs because the WCF process initializer does not inform the host process that the application process is still responding. If the WCF process initializer takes a long time to initialize the COM+ components, the host process assumes that the application process is not responding. Then the host process ends the application process.
