ovn-controller crash when deploying new instance

Solution In Progress - Updated -


  • When deploying a new instance, to be part of a kubernetes cluster, with several security groups attached, we experience a crash in all ovn-controller containers.

  • The error message is:

02770|util|EMER|controller/ofctrl.c:1198: assertion ovs_list_is_empty(&f->list_node) failed in flood_remove_flows_for_sb_uuid()
  • We could reproduce the error on a preprod openstack platform.

  • Do you have some guidelines to workaround this issue or update ovn?

  • Can't manage/scale kubernetes clusters for customers and our needs.
