Proxmox vm network loss

[Nisamudeen]

Hi,

We are having proxmox nodes with version "Virtual Environment 5.0-23 ", we could see some of the vms network are dropped all of a sudden with no errors in node logs. And on vm reboot the network is back again. We had checked all logs meanwhile we are unable to find any information.

Does it mean someone had the same behavior? Is there any workarounds or clue?

I had a similar problem with my containers last night. Had to restart them to get the network to work..

The entire nodes containers (10) and VMs (5) lost connection. Had to restart them all to get them working.

Hi,

below is the only clue I can find it from my logs. My node is having 160 days uptime and the vm ids logged in below had the issues. And this was fixed after container reboot.
