openvswitch hang [closed]
hi guys,
i deploy openstack multi-node with neutron (openvswich + gre). it's work fine but i met a issue that network can't be conneted by the openvswitch hang. so that one of the compute server have this proberm other is work fine.
i have below check: all of the neutron agent looks fine by "neutron agent-list" check. all of the compute nodes looks fine by "nova-manage service list" and check the openvswich server status ,it's looks fine also by "/etc/init.d/openvswitch status" so i try to restart the openvswitch , but i'm failed.
[root@compute3 ~]# /etc/init.d/openvswitch status
ovsdb-server is running with pid 9481
ovs-vswitchd is running with pid 9494
[root@compute3 ~]# /etc/init.d/openvswitch restart

openstack version and os information:

"[ovs-vswitchd] <defunct>" is not looking good. Reboot?
