Description Dan Williams 2019-12-12 16:02:12 UTC

Investigate increasing the default ovn-controller and SBDB probe intervals. The default is currently 5 seconds for both, but Russell says every single non-trivial deployment hits the 5 second limit and drops connections continuously, requiring eg OpenStack to default to 180 seconds.

Perhaps our defaults in OVN upstream/downstream should be changed.

Or dynamically change the probe interval in ovn-controller based on an average of the last recompute times + some amount of slack.

Dynamically changing the probe interval seems a very good idea.
