Even better, another guy on the rhbz reported the mhocko git tree
since-4.9 solves the bug for him too! And it ran another night (4+
total) without problems on my box. Whatever is in since-4.9 fixes it,
as I reported before.
But...

After 30 hours of running vanilla 4.10.0-rc6, the box started to go
bonkers at 3am, so vanilla does not fix the bug :-( But, the bug hit
differently this time, the box just bogged down like crazy and gave
really weird top output. Starting nano would take 10s, then would run
full speed, then when saving a file would take 5s. Starting any prog
not in cache took equally as long.
However, no oom hit. I waited about 15 minutes and things seemed to
bog more, so I rebooted into since-4.9. Maybe if I had kept waiting
the box would have oom'd, but I didn't want to take the chance (it's
remote, and I can't reset it).
I did capture a lot of the weird top, meminfo and slabinfo data before
rebooting. I'll attached the output to this email. Messages show a
lot of "page allocation stalls" during the bogged-down time.
So my hunch at this moment is 4.10.0-rc6 might help alleviate the
problem somewhat, but it's other things you have in since-4.9 that
solve it completely.
Let me know if you need any more testing or some bisecting or
something. I'll keep on running since-4.9 in the meantime. Thanks!
