Public bug reported: The method "neutron.agent.linux.ip_lib.network_namespace_exists" can timeout in loaded systems. We have detected this problem during some capacity tests. During those tests, the controllers are creating and deleting networks; that implies the creation and deletion of DHCP namespaces "qdhcp-xxx" in the same hosts. Adding additional logs (tagged with "SK;"), we found this method was timing out.
