We are having a strange and sporadic abend in some ISV code. So far
all we've got is the IEA995I SYMPTOM DUMP. I've set a SLP to get more.
The PSW points to a perfectly valid ST R7,7 instruction.
There is nothing valid about a ST R7,7 instruction;
that says "store the contents of R7 into location 7
of memory"; this is protected storage; and it is an
odd address.
The strange thing to me is an ILC of 6. How can I get 6 from a 2 bit
field?
Instructions are 2, 4, or 6 bytes in length;
an ILC of 00 -> 2 byte instruction
an ILC of 01 -> 4 byte instruction
an ILC of 10 -> 4 byte instruction
an ILC of 11 -> 6 byte instruction
[ref: Principles of Op., page 6-6]
a ST is 4 bytes; perhaps you need to take the PSW and
subtract 6 and see what instruction is there.
Kind regards,

We just completed z/OS 1.7 upgrade, but the problem seems to have
been there when we were on 1.4.
