If the APPC address space ends due to either an operator CANCEL or FORCE command (messages ATB010I or ATB012I, respectively) or APPC/MVS cannot restart the APPC address space (message ATB006I), the following occurs:

• XCF notifies the members of APPC's XCF group that APPC is unavailable.
• The system shuts down all active LUs.
• The system does not save or restore active APPC conversations, either local and remote. The conversations are lost and the system notifies the invoking applications.
• FMH-5 requests that have been received, but not passed to the appropriate scheduler, are sent an FMH-7 notifying the partner TP of the error.
