Your settings here are somewhat odd.

For example, consider that you reserve at least 30% of memory for exec
and files. Having done so, you can NEVER achieve an anonmax of 95% --
at most, 70% can be used for anons.

I suspect you're setting execmax and execmin way too low -- you end up
with too few pages for executables -- but I haven't seen paging
statistics on your machine so I don't know if that's a problem in
practice.
