SYMPTOMS
========

Mail delivery fails and the Session.log of External shows similar entries:

  A Critical error has occurred
  Data: Error Code~0c, Device Error _14
  Mailbag truncated by up_retries
  Mail transfer failed.

CAUSE
=====

There is a problem accessing the postoffice because External has failed to read
from disk possibly because of a network connection problem. The error "mailbag
truncated by up_retries" means External had a problem at the time it was
processing mail in the referenced mailbag. These errors together suggest a
failure in the network connection.

RESOLUTION
==========

A network trace may be necessary to pinpoint the connection failure. There is a
short-term workaround that works with the MS-DOS MTA only. A setting in the
External.ini will allow External to restart when it encounters a critcal error.
The setting is:

  ReBootOnce

This is not a fix but can be used as a workaround until the cause of the problem
can be determined and resolved.

MORE INFORMATION
================

External will return an error generated by Interrupt 24h in MS-DOS
(Critical-Error Handler).

The "device error = c" means "general failure". Here is the list of other
possible values:
