Most likely causes:
•The CGI process was shut down or terminated unexpectedly before it finished processing the request.
•The CGI process has a flaw and does not return a complete set of HTTP headers.
Things you can try:
•Check the event logs on the system to see whether the CGI process is shutting down unexpectedly.
•Troubleshoot the CGI application to determine why it is not sending a complete set of HTTP headers.
