System Abort
A system abort is a condition experienced
by
the
~APE/iX
operating systern in which either
system or data integrity may be compromised by continued operation. vVhile the causes of
system aborts are many, the result is always the same: the system immediately halts and
displays system abort information on the physical console (Ldev 20). All user activity stops.
A system abort message typically has the following format:
SYSTEM ABORT xxxx FROM SUBSYSTEM xxxx
SECONDARY STATUS: INFO
=
xxxx, SUBSYS
=
xxx
SYSTEM HALT
7,
$xxxx
{this line may not appear}
Use the recovery procedures in Table 5-18 to resolve the problem.

3. Take a memory dump. Refer to the "Taking

4. Restart the system when dump is finished.
If you have a system abort message on the console, it is probably unnecessary to copy down
the hex display pattern. However, if there was nothing printed on the console AND the
hex display looks like that above (it includes a "Bx07" sequence) then you have probably
experienced a system abort which did not identify itself on the console display. In this case,
write the codes down. The Response Center can determine the system abort number from this
information.
