net.ipv4.neigh.default.gc_thresh3=65536

$ curl -Ls https://raw.githubusercontent.com/openshift/origin/master/contrib/tuned/origin-node-host/tuned.conf | grep gc_
net.ipv4.neigh.default.gc_thresh1=8192
net.ipv4.neigh.default.gc_thresh2=32768

Checked tuned-profiles-atomic-openshift-node-3.6.74-1.git.0.e6d1637.el7.x86_64.rpm and it is fixed there, so it only looks like 3.5.x is affected?
