Description Numan Siddique 2022-05-05 20:13:46 UTC
Description of problem:

ovn-controller is crashing.

It can be reproduced as:

ovn-sbctl chassis-add foo geneve 127.0.0.2 
foo_uuid=$(ovn-sbctl --bare --columns=_uuid find chassis name=foo)
ovn-sbctl set chassis $foo_uuid other_config:ovn-chassis-mac-mappings="foo"

After the last command, ovn-controller's crashes on all the chassis.



The issue seems to be already reported u/s a while back - https://www.mail-archive.com/ovs-discuss@openvswitch.org/msg08052.html
