As reported on this bug
HA gate and periodic jobs for master and sometimes newton started to
fail for errors related to memory shortage. Memory on undercloud
instance was increased to 8G less than a month ago, so the problem
needs a different approach to be solved.
We have some solutions in store. However, with the release date so
close, I don't think it's time for this kind of changes. So I thought
it could be a good compromise to temporarily increase the undercloud
instance memory to 12G, just for this week, unless there's a rapid way
to reduce memory footprint for heat-engine (usually the biggest memory
consumer on the undercloud instance)
Any other ideas ?
