I loaded the K17 firmware update today and will see what happens.
I did have a chance to look at the system while in failure mode.
1) Keylink showed the ports idle.
2) Dialing each port separately returned a busy siganal.
3) Dialing the UCD group returned a ring-no answer (yes, I check to see if there were any other members in the VM UCD groups and there were only the three VM ports).
4) After I disconnected KeyLink, the VM rebooted itself. I heard it go through the boot-up beeping, which it usually doesn't do.
