arping can take relative long time (>2 sec), while the global lock is held. The gratuitous arping should not block other threads. The neutron code base already contains a `non-block` version: https://github.com/openstack/neutron/blob/6d2794345db2d7b12502f6e7b2d99e05a85b9030/neutron/agent/linux/ip_lib.py#L732 Please do not increase the lock held time by arping. Consider using the send_gratuitous_arp function from the ip_lib.py . PS.: The same blocking arping also re-implemented in the neutron_lbaas/drivers/haproxy/synchronous_namespace_driver.py. ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
