Salvatore Orlando 2d69f32fb5 Prevent L3 agent looping calls from hanging ... This patch adopts several measures to prevent _sync_routers_task and _rpc_loop from hanging because of subprocess.Popen.communicate not returning. 1) Perform a sleep everytime a command is completed, similarly to what is done in openstack.common.processutils.execute 2) Disable by default GARP, as kernel crashes caused by arping have been observed 3) Prevent a non-critical keyerror in _router_removed from triggering again a full sync, which might put the system under significant load. This patch also adds debug log statements aimed at improving the ability of debugging similar failures.
