Subject CS process killed by kernel OOM
Date Thu, 26 Jan 2017 05:36:37 GMT
Hi there,

We installed 2 new nodes these days. They run on ubuntu (Ubuntu 16.04.1
LTS) with kernel 4.4.0-59-generic. On these nodes (and only on these) CS
gets killed by the kernel due to OOM. It seems very strange to me because,
CS only takes roughly 20GB (out of 128GB), most of RAM is allocated to page
cache.

Top looks typically like this:
KiB Mem : 13191691+total,  1974964 free, 20278184 used, 10966376+buff/cache
KiB Swap:        0 total,        0 free,        0 used. 11051503+avail Mem

This is what kern.log says:

Has anyone encountered sth like this before?
