Sep 23 03:54:08 network1 ovsdb-server: ovs|01253|reconnect|ERR|tcp:127.0.0.1:50814: no response to inactivity probe after 5.01 seconds, disconnecting A lot of those keep appear, and openvswitch always reconnects almost instantly though. I’ve done some research about that particular message, but it didn’t give me anything I can use to fix it.
