 Reason Code (hex)
Explanation
0001-000C
Internal error.

System action
 APPC services are unavailable.  The system rejects
all incoming APPC work.  Work already running on the system completes
or ends. When APPC has ended, normally or abnormally, the system issues
message ATB002I.  The system writes an SVC dump.

Operator response
 Do not send any new work to APPC.  To start
a new APPC address space, do the following:  Wait until the system issues message ATB002I and then enter the
START APPC command.
If the system does not issue message ATB002I, APPC has hung in
the process of ending.  Try entering the FORCE command.
If the system still does not issue message ATB002I after you enter
the FORCE command, the only way to start APPC is to reIPL the system.

System programmer response
 Identify the problem, using the SVC
dump and the APPC component trace records. APPC might have abnormally
ended because of the frequency of abends (two abends within one hour).
 If so, an SVC dump was taken for each abend. The system issues message
ATB005I following the first abend. The abends might be unrelated.
 If
the problem persists, search problem reporting data bases for a fix
for the problem.  If no fix exists, contact the IBM® Support Center. Provide the SVC dump and
the reason code issued by this message.
