Hello all, Like others, we have seen an increase in the amount of messages like those below, followed up by disconnects: 2020-03-19T07:19:47.414Z|01614|rconn|ERR|br-int<->tcp:127.0.0.1:6633: no response to inactivity probe after 10 seconds, disconnecting 2020-03-19T07:19:47.414Z|01615|rconn|ERR|br-ex<->tcp:127.0.0.1:6633: no response to inactivity probe after 10 seconds, disconnecting 2020-03-19T07:19:47.414Z|01616|rconn|ERR|br-tun<->tcp:127.0.0.1:6633: no response to inactivity probe after 10 seconds, disconnecting We have since increased the value of of_inactivity_probe (https://bugs.launchpad.net/neutron/+bug/1817022) and confirmed the Controller connection reflects this new value: --- # ovs-vsctl list Controller ... _uuid : b4814677-c6f3-4afc-9c9e-999d5a5ac78f connection_mode : out-of-band controller_burst_limit: [] controller_rate_limit: [] enable_async_messages: [] external_ids : {} inactivity_probe : 60000 is_connected : true local_gateway : [] local_ip : [] local_netmask : [] max_backoff : [] other_config : {} role : other status : {last_error="Connection refused", sec_since_connect="1420", sec_since_disconnect="1423", state=ACTIVE} target : "tcp:127.0.0.1:6633" --- However, we also see disconnects on the manager side, which the config option does not address: 2020-03-23T11:01:02.871Z|00443|reconnect|ERR|tcp:127.0.0.1:50098: no response to inactivity probe after 5 seconds, disconnecting This bug (https://bugs.launchpad.net/neutron/+bug/1627106) and related commit (https://opendev.org/openstack/neutron/commit/1698bee770b84a2663ba940a6ded5d4...) appear to leverage the ovs_vsctl_timeout value (since renamed to ovsdb_timeout), but the inactivity_probe for the Manager connection does not appear to be implemented. Honestly, I'm not sure if that code path is used. --- # ovs-vsctl list Manager _uuid : d61519ba-93fc-4fe5-b05c-b630778a44b0 connection_mode : [] external_ids : {} inactivity_probe : [] is_connected : true max_backoff : [] other_config : {} status : {bound_port="6640", n_connections="2", sec_since_connect="0", sec_since_disconnect="0"} target : "ptcp:6640:127.0.0.1" --- Running this by hand sets the inactivity_probe timeout on manager connection, but we'd prefer to use a built-in method, if possible: # ovs-vsctl set manager d61519ba-93fc-4fe5-b05c-b630778a44b0 inactivity_probe=30000 Any suggestions? Thanks, James
