Public bug reported: If there are multiple ovs-agents instances running on a single node then trunk re-acts on all ovsdb events. That means if a port is removed from a trunk bridge then all agents will attempt to clear resources around given trunk bridge. This leads to race condition where foreign ovs- agents removes trunk bridge before the correct one. As foreigh ovs- agents have different integration bridge names, they don't clear up properly patch ports on br-int side.
