To debug memory leaks, we need periodic statedumps of respective processes.
Please provide the statedumps.

I suspect that you are hitting
https://bugzilla.redhat.com/show_bug.cgi?id=1694612. This bug is addressed
in release-5.6

> Hi everyone!
> I'm using a Gluster 5.4 Setup with 3 Nodes with three volumes
> (replicated) (one is the gluster shared storage).
> Each node has 64GB of RAM.
> Over the time of ~2 month the memory consumption of glusterd grow
> linear. An the end glusterd used ~45% of RAM the brick processes
> together ~43% of RAM.
> I think this is a memory leak.
> I made a coredump of the processes (glusterd, bricks) (zipped ~500MB),
> hope this will help you to find the problem.
> Could you please have a look on it?
> Download Coredumps:

> Kind regards
