Troubleshooting bizarre 'wrong console' issue

I've run into a strange issue using Proxmox 2.x where it displays the wrong VNC console.

root@kvm1:~# pveversion
pve-manager/2.1/f32f3f46

Two weeks ago I had this problem and I figured I had just messed something up. I ended up stopping all my virtual machines and rebooting the physical hardware. It resurfaced today, and I'd like advice on how to help troubleshoot it when it happens again.

I have three proxmox machines in a cluster and here's the basic config:

KVM1 runs 5 virtual machines: support, windb7, mx1, windb, ltsp1
KVM2 runs 2 virtual machines: dc1, rds1
KVM3 runs 3 virtual machines: db1, jmf-rds1, vpn

All three machines are on the same network (10.47.0.1, 10.47.0.2, and 10.47.0.3)

Yesterday I created 'windb7' on KVM1 to test the upgrade path for a client application. Everything worked 'normally'. I set up Windows 7, and ran my tests. While I was testing, I pulled up the console for 'windb', signed in, and copied some data (from within the guest) to 'windb7'. At the end of the day, I locked my workstation with everything still working and left.

This morning I received a frantic call that 'windb' was down. I connected in remotely and found my browser session had timed out and I had to re-login. I did, then I right-clicked 'windb' and opened the console. I was greeted with the console for 'rds1' which is on KVM2. So I brought up the console for 'rds1' and I got a blank screen. I'm assuming it pulled up 'windb' which was crashed.

I brought up a few other consoles and found most of them were pointing to completely different virtual machines. 'db1' was greeted me with the 'mx1' login prompt.

I opened up all the consoles and shutdown the guests. I dug through syslog on KVM1, 2, and 3 and found nothing to indicate an error. I looked through dmesg and didn't see any issues with the iscsi connections to the NAS boxes.

Any pointers on where I should look or what I should gather next time this happens?
