Hi Toni, Yes, that is one thing to try which is probably how the issue happened, since this error leg is very infrequent. The other thing I was thinking is we might be able to manually trigger this code path by removing (or moving) the neutron-keepalived-state-change script out of the way and create an HA router. I think that would trigger an exception that would delete the router and go through this path. You'd just have to watch for "Error while initializing router $id" in the l3-agent log. -Brian
I don't think this traceback is related to the change, it actually looks like this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1470784 https://bugs.launchpad.net/neutron/+bug/1706750 The code in OSP10 isn't exactly the same, so I'm not sure it can just be picked there, we'd have to look further.
I would have to look into that bug separately as I'm not sure that backport won't cause other problems.
