      There was no coredump produced from this assertion failure. The crash was only seen on one node. All nodes were printing:

      2024-10-28T16:58:44.283Z|04438|pinctrl|WARN|Invalid IPv6 prefixes:

      due to a bug in OVN-Kubernetes:

      https://github.com/ovn-org/ovn-kubernetes/pull/4810

       

      Not sure if the log is related at all, but thought I would include that info . Will attach DBs, and full log.
