<div>Thank you for looking into this. I indeed also suspect it
has something todo with the 7.X client, because on the 6.X
clients the issue doesn't really seem to occur.</div>
<div>I would love to update everything to 7.X, But since the

<p>Olaf, based on your email. I did try to upgrade a 1 node of a
3-node replica 3 setup from 6.10 to 7.8 on my test VMs and I found
that the self-heal daemon (and the bricks) came online after I
restarted glusterd post-upgrade on that node. (I did not touch the
op-version), and I did not spend time on it further. So I don't
think the problem is related to the shd mux changes I referred to.
But if you have a test setup where you can reproduce this, please
raise a github issue with the details.<br>
</p>
Thanks,<br>
Ravi<br>

<div>Hopefully that issue will be addressed in the upcoming
release. Once i've everything running on the same version i'll
check if the issue still occurs and reach out, if that's the
case.</div>

I did check the lines on statedump and it could be
happening in protocol/clinet. However, I did not find
anything suspicious in my quick code exploration.<br>
</div>
<div>I would suggest to upgrade all the nodes on latest
version and the start your work and see if there is any
high usage of memory .<br>
</div>
<div>That way it will also be easier to debug this issue.<br>

<div>The issue seems to be triggered by a program
called zammad, which has an init process, which runs
in a loop. on cycle it re-compiles the ruby-on-rails
application.</div>
<div><br>
</div>
<div>I've attached 2 statedumps, but as i only
recently noticed the high memory usage, i believe
both statedumps already show an escalated state of
the glusterfs process. If it's needed to also have
them from the beginning let me know. The dumps are
taken about an hour apart.</div>
<div>Also i've included the glusterd.log. I couldn't
include mnt-docker2.log since it's too large, since
it's littered with: " I [MSGID: 109066]

<div>However i've inspected the log and it contains no
