Yes, so the bug has been fixed upstream and the backports to release-7 and
release-8 of gluster pending merge. The fix should be available in the next
.x release of gluster-7 and 8. Until then like Nir suggested, please turn
off performance.stat-prefetch on your volumes.

The screenshot "engine.png" show gluster bug we discovered a few weeks ago:
https://bugzilla.redhat.com/1823423
Until you get a fixed version, this may fix the issues:
# gluster volume set engine performance.stat-prefetch off
See https://bugzilla.redhat.com/show_bug.cgi?id=1823423#c55.
Krutica, can this bug affect upstream gluster?
Joop, please share the gluster version in your setup.
