    Yes this was done due to one of the points mentioned by you in the earlier comments to
log a full stack trace on each heartbeat (each time we collect metrics). I will remove it
and make changes to log only once.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
