      There's nothing obvious in this collectinfo. And top doesn't show beam as CPU consumer at the moment collectinfo was gathered. On the other hand I'm seeing all load averages be above 10. And that's clear sign of some cpu usage.

      And I've also confirmed that in past hours machine was idle at least w.r.t. K/V ops.

      May I ask you direct access to this box ?

      AFAIK we concluded investigation with understanding that 2.0.1 should be better. 2.0.2 is known to be even better.
