PVE 5.2 / LXC / Issues with containers.

[devinacosta]

I have the very latest PVE 5.2 installed, fully patched to the latest versions. I have what appears to be the bridge configured correctly, what is bizarre for me is that I have a single container running and you can log into the container but then about exactly (30 seconds) the connection just dies hard. You then have to disconnect hard, then re-connect and your connection will stay active again for another 30 seconds. What would be killing it after 30 seconds?

The container that I have running isn't doing anything strange, the network for the VM is configured as:
net0: name=eth0,bridge=vmbr0,gw=10.0.1.3,hwaddr=46:46:18:36E:53,ip=10.0.6.221/20,type=veth

I haven't seen this behavior before, so I'm not quite sure what to think.
