Hi Paolo:
Do you mean that the same hash for nat con and conntrackcon will trigger
this issue? I am also encountering this assert issue now, but I have not
figured out the clear emerging scenario?
Can you provide a test case that can emerge?
Best regards.

Hi Paolo:
Is this logic wrong for streams with the same 5-tuple hash to hit the same
CT stream table?
So if “avoid to include two keys with the same hash belong to the same
connection even for the nat case ”, is it a waste of CT's table resources ?

Hi Paolo,
Should we combine this patch too?

Hi Paolo,
I'm interested in your statement of "expired connections (but not yet
reclaimed)". Do you think that shortening conntrack timeout policy will
help? Or, should we make it larger so there will be fewer conntrack table
update and flush attempts?
Best regards.

Hi Michael,
I assume that your k8s cluster is on the same subnet, right? Would you mind
testing it by shutting down one of etcd instances and see if this bug still
exists
Hi Paolo,
Would you mind to explain this to me? Currently, I'm still looking for
compiling options of installed OVS-DPDK from Ubuntu repo. After that, I'll
try your patch and compile it with same options.

Hello,
thanks for reporting this.
I had a look at it, and, although this needs to be confirmed, I suspect
it's related to nat (CT_CONN_TYPE_UN_NAT) and expired connections (but
not yet reclaimed).
The nat part does not necessarily perform any actual translation, but
could still be triggered by

Hi Michael,
Is your patch working on the same subnet unreachable traffic too. In my case,
crashes happen when too many unreachable replies even from the same subnet. For
example, when one of the etcd instances is down

Hi,
we are about to roll out our new openstack infrastructure based on yoga and
during our testing we observered that the openvswitch-switch systemd unit
restarts several times a day, causing network interruptions for all VMs on the
compute node in question.
After some research we found that
