Hi All



         I’m encountered a very strange problem that ovs-vswitchd exited silently without any exceptions while ovsdb-server running normally, I’m using openvswitch 2.9.2

I didn’t find any valuable log except that

ovs|00001|unixctl|WARN|failed to connect to /var/run/openvswitch/ovs-vswitchd.5168.ctl

ovs-ctl[303320]: 2019-09-05T03:12:28Z|00001|unixctl|WARN|failed to connect to /var/run/openvswitch/ovs-vswitchd.5168.ctl

ovs-ctl[303320]: ovs-appctl: cannot connect to "/var/run/openvswitch/ovs-vswitchd.5168.ctl" (Connection refused)



See the details below.
