@Lukasz:
Thanks Lukasz for your thoughts - you confirm my concerns.
Trying to answer your question:
- reproducible
- it failed on our P9 machine at 100%
- I don't have another P9 to check if it is specific to "that" machine or P9
in general
- I was deploying a P8 system to have some comparison
- bug 1839065 blocked me from using the same workload, so the results are
unreliable at
best
- How frequently
- in the affected system on every restart of the service (while huge guest
was active)
- easy (or not) to fix:
- from what I saw in the traces it looked like more out of bounds access.
if that was right then it would be (too) much changes and realyl complex as
that kind was in
many places; but towards the end I got convinced that it might have been a
red herring after
all. Never the less unless it is further debugged the complexity is
somewhere between rather-
complex and unknown
IBM was reporting this bug here for P9, maybe they are the ones with the P9
machine park (different configurations). If it is important to them they can
asses and let us know about details for bug 1836913 and we might hold back this
SRU for now (being unsure how often we might trigger this).
OTOH any numad service restart will trigger it, it is not that we'd add the bug
with this proposed update.
For now I'd say leave it in proposed and we wait if there is IBM feedback on
bug 1839065 or bug 1836913.
