Loosing network connectivity to containers
type: item
description: Hi, I have an OpenVZ HW node setup on OVH with vRack. Once routes are setup for the vRack it works well but, randomly after every 2-3 hours i loose connectivity from and to virtual machines. I can restore connectivity after doing service vz restart .. i am trying to figure what drops the connection, and why reloading the CT's would fix the issue. While CT's are down i run tcpdump -i eth1 And i see ping requests i do from the outside : 12:25:13.998153 ARP, Request who-has 192.x.x.x tell 192.x.x.x, length 46 From the CT's if i ping 8.8.8.8 i get the following on the HW node tcpdump : 12:26:38.771655 IP 192.x.x.x > google-public-dns-a.google.com: ICMP echo request, id 31618, seq 1, length 64 12:26:39.005798 ARP, Request who-has 192.x.x.xtell 192.99.x.x, length 46 12:26:39.176141 ARP, Request who-has 192.x.x.xtell 192.99.x.x, length 46 12:26:39.771720 IP 192.99.x.x> google-public-dns-a.google.com: ICMP echo request, id 31618, seq 2, length 64 Any idea would be greatly appreciated.
