we just hit the same, applied patch STREDG0A, but one week later the same
SA.
Further dump analysis showed that a fine POSIX script with piping caused
the problem.
Process tree:
JSMAIN
CI
SH
SH
CUT
SORT
SORT
Multiprocessor system and multiprocessing (this pipe) and high memory
utilization may result in a memory page absent error and this SA.
Recommendation of the German RC: eliminate the pipe (callci SHOWJOB|grep -c
...|sort ...|sort ...)
by working in single processes with temporaer files:
callci SHOWJOB > pipe_0_file
grep -c pipe_0_file > pipe_1_file
sort ... pipe_1_file > pipe_2_file .... and so on ....
On the other hand, the original piped script worked fine for approx 2
months 80 times a day without causing this SA ... but I changed it to the
recs ...

Subject: System Abort 1047, Subsystem 101
Hello,
I am coordinating the testing of DCE/3000 on a MPE/iX 5.5 system. One of
the
test programs is designed to create some sockets, communicate with another
process that listens on a socket and then create multiple threads and
listens
on the sockets it has created. (Please bear with me if the explanation is
not
totally clear as I am passing on the programmers comments.) The result of
running this program was a System Abort 1047, subsystem 101 which my Error
Message manual tells me is "Memory Manager Page Fault while interrupts are
disabled". I made a dump and made a PICS call which resulted in them
sending
me a tape with some additional patches. I loaded the patches but I still
get
the same result. Someone suggested that it might be a resource issue but
can
anyone shed any light on this while I am waiting for HP to analyse the dump
tape?.
Cheers,
John Dunlop
