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.
