PC MTA: Read Error During Data Exchange (122152)

READ ERROR

A read error may appear in the SESSION.LOG file as well as on the screen when the Message Transfer Agent (MTA) in version 3.20 of Microsoft Mail for PC Networks is started on an X.25 network (COMMTYPE=X25EICON in EXTERNAL.INI) with the -l -v -q command line parameters. The read error includes three numbers that identify the cause of the error, the diagnostic code, and the Eicon network error: 00 00 0A.

The error occurs after a data exchange when the calling MTA issues a clear request and then mishandles the following clear confirm response. The error causes no problems and can be ignored.

NOTE: The read error may be a real error; if so, it will be followed by a specific error which will usually end the data exchange. The cause or diagnostic codes may still be set to zero.

MORE INFORMATION

Below are two examples of SESSION.LOG files. The first example shows the minor problem detailed above. The second shows a real read error which should be further trouble-shooted. The nature of the two read errors can be differentiated by the other messages nearby in the SESSION.LOG.
