Please look at the attached image. This traffic is using around 200KB/s of constant bandwidth and is exhausting our allocated monthly bandwidth on our 2 VPS.
>>> Self-heal-daemon tries to check if there is anything that needs healing every 10 minutes. Those RPCs are lookups. Could you check from the tcpdump if it is generating from self-heal-daemon? Which version of gluster are you using? I think there is a way to increase this 'time' in latest versions.
