      1.ep_commit_time
      2. rsize_beam : > 2.8G on some points

        Per bug scrub, engineering must at least identify and understand the root cause of this behavior. Assuming a fix may require cross-components change, the actual delivery of the fix may schedule into the next release after 2.0.1.

        Ketaki, per bug scrub, please collect atop from the 2nd running of the test. If and only if possible though understanding that it is over ec2 environment and longevity test. Thanks.
