All IPs Fail
We have 4 servers all connected to the same VLAN for VPS hosting. All servers are running CentOS 64bit with OpenVZ installed.
One of our servers, all of the IPs fail. We figured out the first time it happened it was NEIGHBOR_DEVS in the vz.conf file which it was saying "all" and we changed it to "detect" and it all worked again. Recently it all went down again and we got told to change it back to "all" so we did, rebooted VZ and everything worked again. Now today, all IPs failed again, I rebooted VZ, nothing, I rebooted the server and everything came back up again.....
Can anyone tell me why this is happening? It's killing my business daily..
