I found related issues that might be helpful:

• ovs-ovn has been crashed randomly #3196
  This issue was referenced by another issue related to connection failures and long retry times, which might be relevant to your problem with OVS not connecting to the OVS DB.

• ovs-ovn pod异常重启，node节点网络闪断，node上pod全重启 #3519
  The suggested solution for this issue was that the problem was unrelated to kube-ovn, which might indicate that similar issues could have external causes.

• Upgrade OVN and OVS #2250
  This issue was referenced by another issue concerning slow initialization in large-scale clusters, which might provide insights if your environment is similar.
