multiple deletes in firewall tempest case: "test_create_show_delete_firewall" cause l3-agent throws unexpected exception: "FirewallNotFound".
I am running tempest against kilo release, after running the neutron case: "test_create_show_delete_firewall", my l3-agent reports the following errors and exceptions:
In this tempest case:
I found delete firewall will be called twice, the second delete_firewall(in the method addCleanup), will be called immediately after the first(self.client.delete_firewall).
This looks like an async call locking problem, I don't know if the current log/implementation/behavior is expected or unexpected.
