Build Update for ovn-org/ovn
-------------------------------------

Build: #539
Status: Still Failing

Duration: 1 hr, 9 mins, and 17 secs
Commit: 4f366b7 (branch-20.09)
Author: Renat Nurgaliyev
Message: northd: Don't poll ovsdb before the connection is fully established

Set initial SB and NB DBs probe interval to 0 to avoid connection
flapping.

Before configured in northd_probe_interval value is actually applied
to southbound and northbound database connections, both connections
must be fully established, otherwise ovnnb_db_run() will return
without retrieving configuration data from northbound DB. In cases
when southbound database is big enough, default interval of 5 seconds
will kill and retry the connection before it is fully established, no
matter what is set in northd_probe_interval. Client reconnect will
cause even more load to ovsdb-server and cause cascade effect, so
northd can never stabilise. We have more than 2000 ports in our lab,
and northd could not start before this patch, holding at 100% CPU
utilisation both itself and ovsdb-server.

After connections are established, any value in northd_probe_interval,
or default DEFAULT_PROBE_INTERVAL_MSEC is applied correctly.
