OK, I figured the good ole' dumpreader (that's me) could bring a few
details. You wrote :

Means process aborted while critical (shoulnd't have aborted, since it was
flagged by MPE/iX as critical, hence the system itself kind of committing
suicide) from Process Management (subsys 102). Seriously implies that
Process Management somehow manages processes. Not a big surprise, huh ?

That's an invalid pointer (-55), or more precisely, an invalid target
address alignment causing a data memory protection trap, from Virtual Space
Manager (the module of MPE which handles virtual addressing, including
pointers). Helps trace the root cause of the system abort. Or, at least,
tells the dumpreader (if there's a dump, that is ...) where to start.

Same as SA 1458, in hex form. Also indicates the system has logically come
to a halt due to software (halt 7)

Too bad. Otherwise, I would have asked for a memory dump. It's very hard to
figure out what a general purpose system abort such as a 1458 can be without
a memory dump.

Hope this clears the mud, somehow ...
