Prevalent error using redirectors and OSE remote

Technote (FAQ)
Problem
The following error appears in the plugin trace of people with possible connection problems between the webserver and the appserver:
Solution
The following is an error we see a lot in the trace.log.whatever file...followed by a description of what it means:

ERROR (s):
-------------
Tue Dec 5 14:34:18 2000 - Error - ERROR: In do_service_time_request, enter_callback_mode failedTue Dec 5 14:34:18 2000 - Error - Error passing service/run request ... error 1 on clone 0
Tue Dec 5 14:34:18 2000 - Error - router_service : Failed 1

POSSIBLE CAUSE:
--------------------------------
I have traced through the logical path within the Plugins that report the messages. I believe that these errors were generated in an attempt to send a client request across a connection that is not "alive" or available for some system related reason.

The do_service_time_request routine is called from a system management function that determines which clone is available to service the current request.

The message "Error passing service/run request" indicates that the actual attempt to submit the request to the clone has failed. This is different than the request being submitted successfully and the clone not responding.

The enter_callback_mode failed message in this case can be regarded as a side effect to the main error: router_service failed. I believe the callback functions are attempting to relay the Application Server response to the WebServer, If the request was never sent, the servicing of a response would subsequently fail.
