That makes sense, but its been nuked as I'm running another test backup 
right now, and those left overs are an error. I am trying to get my 
script to send kmail a dcop message, but amanda apparently has no rights 
to use dcop. msg posted to trinity about that.

The next time it happens I will investigate before I nuke the trash.

I don't know, and since I no longer have the failures data, not a lot of 
use grepping the logs.

But it failed on a level 0 of /GO704/home this time, so I'll post a 
separate message with those details when collected.
