The SECOND brick on the SAME host is NOT affected, i.e. no disconnects!
As I said, the network connection is fine and the disks are idle.
The CPU always has 2 free cores.

It looks like I have to downgrade to 3.4 now in order for the disconnects to stop.</pre>

    Hi Micha,<br>
    <br>
    Thanks for the update and sorry for what happened with gluster
    higher versions. I can understand the need for downgrade as it is a
    production setup.<br>
    <br>
    Can you tell me the clients used here ? whether it is a
    fuse,nfs,nfs-ganesha, smb or libgfapi ?<br>
    <br>
    Since I'm not able to reproduce the issue (I have been trying from
    last 3days) and the logs are not much helpful here (we don't have
    much logs in socket layer), Could you please create a dummy cluster
    and try to reproduce the issue? If then we can play with that volume
    and I could provide some debug build which we can use for further
    debugging?<br>
    <br>
    If you don't have bandwidth for this, please leave it ;).<br>
    <br>
    Regards<br>

        <p>Hi Micha,</p>
        <p>I have changed the thread and subject so that your original
          thread remain same for your query. Let's try to fix the
          problem what you observed with 3.8.4, So I have started a new
          thread to discuss the frequent disconnect problem.</p>
        <p><b>If any one else has experienced the same problem, please
            respond to the mail.</b><br>
        </p>
        <p>It would be very helpful if you could give us some more logs
          from clients and bricks.  Also any reproducible steps will
          surely help to chase the problem further.</p>
