Thanks Dumitru, I
Good to know. Yes, I am using 20.03.
Will try to upgrade.

The change in external-ids is not monitored by ovn-controller any more
after version 20.06. Probably you are still using an older version?

Hi,
Is log file rotation and compression supported for all
OVN services?
How is the time stamp time zone determined by logging?
Is it /etc/localtime, hardcoded UTC, or anything else?
Thanks!

Is the changes made by Neutron liveness-check in SB properly handled
by inc_proc_eng?
Given my testing scale, even the frequency is lowered by that fix,
ovn-controller still takes quite lot of CPU and time to compute SB.
Thanks!

The raft probe is disabled if you use the latest version of OVS, e.g.
2.13.1.

ovn-controller is using UNIX socket connecting to local ovsdb-server.
Inactivity probe doesn't seem to be the cause of high cpu usage.
The wakeup on connection to sb-db is always followed by a "unreasonably
long" warning. I guess the pollin event loop is stuck for too long, like
10s as below.

This commit fixes a case where may-exist flag was not honored.
When the nat type and logical ip both match for snat, but the
external_ip is not the same, the may-exist flag was being ignored.
