Hi Ashish,
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.
I would love to update everything to 7.X, But since the self-heal
daemons

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.
Thanks,
Ravi
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.
Thanks Olaf

I checked the statedump and found some very high memory allocations.

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.
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 .
That way it will also be easier to debug this issue.

*Subject: *[Gluster-users] possible memory leak in client/fuse mount
Dear Gluster Users,
I've a glusterfs process which consumes about all memory of the
machine (~58GB);
# ps -faxu|grep 17317
root 17317 3.1 88.9 59695516 58479708 ? Ssl Oct31 839:36
/usr/sbin/glusterfs --process-name fuse
--volfile-server=10.201.0.1
--volfile-server=10.201.0.8:10.201.0.5:10.201.0.6:10.201.0.7:10.201.0.9
--volfile-id=/docker2 /mnt/docker2
The gluster version on this machine is 7.8, but i'm currently
running a mixed cluster of 6.10 and 7.8, while awaiting to proceed
to upgrade for the issue mentioned earlier with the self-heal daemon.
The affected volume info looks like;
# gluster v info docker2
Volume Name: docker2
Type: Distributed-Replicate
Volume ID: 4e0670a0-3d00-4360-98bd-3da844cedae5

Options Reconfigured:
performance.cache-size: 128MB
transport.address-family: inet
nfs.disable: on
cluster.brick-multiplex: on
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.
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.
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] [dht-rename.c:1951:dht_rename] 0-docker2-dht"
However i've inspected the log and it contains no Error
message's all are of the Info kind;
which look like these;
