109: ZX25-EVT-LCN-ERROR
ZEMS-TKN-EMPHASIS
contains the value ZSPI-VAL-TRUE, indicating that this event is a critical event.
This token is described in the EMS Manual.
ZEMS-TKN-CONSOLE-PRINT
contains the value ZSPI-VAL-TRUE. This token is described in the EMS Manual.
(ZEMS-TKN-) CPU, CRTPID, GENTIME, LOGTIME, PIN, SYSTEM, and USERID
are standard EMS tokens described in the EMS Manual.
In the message text, ldev corresponds to the value of ZEMS-TKN-LDEV.
The value aaaa in the text message indicates which X.25 logical channel is in error.
The value bbb in the text message is 122, indicating file-system error 122 (the LCN
was reset by the X25AM subsystem).
The value ccc in the text message gives more information about the error, and it can
have the following values:
Cause. A path switch occurred because of an operator request or because the X25AM
subsystem detected an error on the specified logical circuit.
Effect. User requests are aborted, and X25AM resets the LCN. The application should
do an end-to-end recovery.
Recovery. If path switches caused by errors occur often or if the error persists,
examine a trace to determine the cause of the error. The cause is most likely a remote
bug or configuration problem.
If the path switch is caused by an operator request, this event message is an
informative message only; no corrective action is needed.
