OVN ndb container restarted

Solution In Progress - Updated -


  • We saw the OVN ndb container restarted in the same time of the issue.

  • We were able to recover coredumps on some computes but nothing in the controllers and the following stack is seen:

  • In addition, a user brought us up that instances on an internal network also has a network outage without FIP and unbound port.
