Hello,

I have a very strange problem that cropped up. I have been running Proxmox for many months with no problems. A few days ago, it started taking a long time to load the Proxmox administration page. When I ping it is usually fails but every once and awhile one gets through. I can still get to all my guests though. My backup snapshots are still taking place on schedule. The hosts and guests all are running through the same NIC. I rebooted the host, rebooted my router and switch. I have tried getting to the page with different browsers and PCs. I cannot ssh to the machine. I tried logging into the host computer locally with a monitor and going an aptitude update && upgrade. It fails with a "temporary failure resolving 'security.debian.org' " error message, something is clearly wrong with the networking on this but I have made no changes to it.

My network interface setup is as follows:

auto lo
iface lo inet loopback

iface eth0 inet manual

auto eth1
iface eth1 inet static
address 192.168.1.4
netmask 255.255.255.0

iface eht2 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.1
bridge_ports eth0
bridge_stp off
bridge_fd 0

auto vmbr1
iface vmbr1 inet static
address 192.168.1.3
netmask 255.255.255.0
bridge_ports eth2
bridge_stp off
bridge_fd 0


Thank you, any help would be greatly appreciated.
 
I also now noticed when connected with a monitor to the host:
r8169: eth1: link down
r8169: eth1: link up

Every time it goes "up" it seems like I can get to the administration page for a minute and then it stops working.
 
hardware failure? or cable/switch?

=> change components.
 
Plugging my proxmox box directly into my router solved the problem, the switch must have some bad ports... thank you
