Public bug reported:

We had:
watch_log_file = true

Set on our neutron agents. We have DVR enabled and were seeing
significant slowdowns on fip changes. Kevin Benton and I narrowed it
down to watch_log_file = true. It seems to be using blocking calls that
prevent eventlet from performing asyncio properly. Setting it to false
immediately resolved the issue.

Can:
 1. The bug be fixed
 2. The gate checks be updated to set watch_log_file = true by default so that its tested in the future?

Please?


Further details:
Mitaka RDO on CentOS 7.2. DVR enabled, L3HA disabled.

Thanks,
Kevin
