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