I have a 64gb ram node running centos 6.5 latest updates
for whatever reason i have 1gb swap
it runs a solusvm slave with kvm boxes set up and running
i have vm.swappiness=0 in sysctl.conf and also manually set it.
the qemu-kvm pids are eating swap though and once it fills they get killed prolly by the kernel
here’s a top withy Op[enter]
