This is actually hitting two different issues from the two bugs:
- 191510 is about "ARC isn't greedy enough" on huge-memory machines,
and from the osreldate that bug was filed on 9.2, so presumably is
- 187594 is about "ARC is too greedy" (probably mostly on not-so-huge
machines) and starves/drives the rest of the system into swap. That
I believe came about as a result of some unrelated change in the
10.x stream that upset the previous balance between ARC and the rest
of the VM, so isn't a problem on 9.x.
