      Hello Pranith,

      The version I am using is 3.5.1.1

      I did a wireshark capture and from looking at gluster
        information found that RPC lookup is being made for random
        files.

    In other response Niels pointed out how to check for it.

    You can also attach the capture file so that we can take a look at
    it.

                Hello,

                I have setup gluster in replicate type and its
                  working fine.

                I am seeing a constant chatting between the hosts
                  for lookup call and lookup reply. I am trying to
                  understand as to why this traffic is being initiated
                  constantly. 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.

                The configuration I have for Gluster is:

                  [guru@srv1 ~]$ sudo gluster volume
                    info
                  [sudo] password for guru: 

                  Volume Name: gv0

                <Mail Attachment.png>

                Please suggest how to fine tune the RPC
                  calls/reply. 

                Thanks,
                Gurdeep.
