Windows 7 client multi-threaded concurrent invocations VxWorks server-side Dcom remote component, when the number of threads more than six, the client will abort, return:

"Untreated exception:
Untreated Exception: System.Runtime.InteropServices.COM Exception: remote procedure call failed
And did not perform, (exception from HRESULT: 0 x800706bf). "

Dcom interface class is with VxWorks dcomwizard lead generation, a very simple interface, was introduced into the int value,

Virtual HRESULT MintIn para (INT *)=0;

//implementation

Para STDMETHODIMP IntinoutImpl: : MintIn (INT *) {
Printf (" printf % d ", * para);
Return S_OK.
}

Someone used the remote invocation Dcom components, Daniel, please help see what reason, thank you,
