Hi,
This started 2 days ago, Proxmox 22.6.32-19-pve #1 SMP

I have a windows server 2012 container. I tried to download a 3.7 GiB file from Microsoft site. at 99% the server lost all connectivity. The WAN IP address could not be pinged from proxmox host or anywhere else. The windows VM could not ping anything. Rebooting the container did not fix it. I have to reboot the proxmost host machine to restore. Now it does this after just a few seconds of attempting a download.

This is almost like a fail2ban rule. Fail2ban is not installed.

ps aux | grep fail2ban does show a process, which I located on another linux openVZ container and stopped. As I needed the windows server up as soon as, I have simply not tried to download again so I don't know is this solved the problem, but it should not be affected by fail2ban running in a different container no?

iptables -- list showed no blocks in either the container or the proxmox host. Completely different set of rules as expected.
there are no bandwidth limits on the windows server container (or any container)
I tried restarting the vmbr0 bridge it is connected to. Only that container cannot restore connectivity without rebooting proxmox.
I tried doing /etc/init.d/networking restart ,, hmm, ok , no containers recovered from that.


Any ideas what is happening here?
Need more info?
Anything else I could try to find out what is going on here?

Many thanks in advance.

Hi Spirit,
No, all set as rtl 8139. Now you mention it, I should try changing to Intel E1000, I didn't want to have to install any drivers in the guests.

yes, don't use rtl 8139, they are not stable.

e1000 or virtio (if you want more performance)

just stable is fine :) . Thing is it has only just started doing it, been up for almost 10 months now. I did notice that the download speeds were higher than in the past, 1.5 and 1.6 MiB, rate limit per single connection incoming from international connection was lower before.

The first download was around 800KiB untill the 99% mark when it flaked out. All downloads since have started at 1.5/6 and flaked out in 3 or 4 seconds.

Thanks for the suggestions. I need to wait a couple days before I can test it again. It does cause a lot of disruption when I have to take all the containers down.
