Hello,
we have a problem with ovn in connection with neutron dynamic routing (which is
now supported with ovn). We can announce our internal networks via BGP and the
VMs in this network can also be reached directly without nat.
But if we attach a public floating ip to the internal self service

Hi Paolo,
I installed the patch for 2.17 on april 6th in our test environment and can
confirm that it works. We haven't had any crashes since then. Many thanks for
the quick solution!
Best regards
Michael

Hi,
I have some news on this topic. Unfortunately I could not find the root cause.
But I managed to implement a workaround (see patch in attachment). The basic
idea is to mark the nat flows as invalid if there is no longer an associated
connection. From my point of view it is a race condition.
you can ask Neutron
team for advice and help (we use IRC), or just write a mail to Openstack

with [Neutron] in the subject.

Hi,
from my perspective the patch works for all cases. My test environment runs
with several k8s clusters and I haven't noticed any etcd failures so far.

Hi,
yes our k8s cluster is on the same subnet. I stopped one of the etcd nodes
yesterday which triggers a lot of reconnection attempts from the other cluster
members. Stilll no issues so far and no ovs crashes
