"I2" means "Internet-2".  I assume that "I1" means the commodity
Internet.  Please correct me if I'm wrong.

This indicates a problem with the operating system because a user

I'm on Tornado now as the user "ldm" and LDM 6.0.13 is running.  I assume
you started it just after you rebooted the computer.

I'll be poking around.

I believe that you were losing data when the LDM 5 was running.
