Inside an ISAPI extension, I make a call to

LPEXTENSION_CONTROL_BLOCK->ServerSupportFunction with a a dwHSERRequest
value of HSE_REQ_SEND_RESPONSE_HEADER_EX

This works fine for a long time, even several days, then the Web service
will crash with the error "System message number 997: Overlapped I/O
operation is in progress" being reported by my application at the same time
of the crash (consistently).

I cannot find anything on Microsoft's website that points to that error in
that particular call. Any ideas?
