Servers are now running on 4.10 kernels, so I guess no one cares about
4.8 anymore.

As original poster, if I didn't continue to post oom dumps, perhaps
things started to peter out on 4.8.0-39 or later.
What was particular about the load that triggered this bug was heavy IO
putting cache pressure on ext4 on a system where there's zero locality
of reference in anything read from or
Thanks.
By the way, also confirming that the patch works here (have been running
the patched kernel for 3 days now). Running on hardware Super Micro
X9SCL with an Intel 82574L NIC.

** Description changed:
Same as #1655842 - Started seeing oom-killer on multiple servers
upgraded to 4.4.0-59.
Unlike #1655842, also seeing the same oom-killer on multiple servers
updated to 4.8.0-34.
First upgraded them all 4.8 servers 4.8.0-36, then downgraded a few to
4.4.0-63
No OOM on servers running 4.4.0-63 just yet, but the memory usage on
them is weird to say the least. The Buffer/SLAB ratio is completely
different from 4.4.0-57.

Title:
"Out of memory" errors after upgrade to 4.4.
This is the reported /proc/meminfo Buffers usage for 4 different kernel
versions. We got the same OOM call traces on both 4.4.0-58 and
4.8.0-34, I highly doubt that to be a coincidence.

Yes they are, I'm seeing the same exorbitant memory usage that we had on
4.4.0-58 as am currently getting on 4.8.0-36.
