I do not think there is much more we can do on this bz without core dumps. Since case is closed, I'm going to also close this bz. Please re-open or create a new issue if that is needed. In order to collect core dumps in the OCP, you use the command: oc adm must-gather --dest-dir="./netwowk_ovn" -- gather_core_dumps Granted we have that, we can ask the OVN core folks for help to see if they we explain why we had the following issue in ovn-northd.
