Apologies for not keeping my last posting on the list (unintentional - I just hit reply rather than selecting reply-all from the drop-down list)
 
The client does not have a disklist file and I'm pretty sure its not a server for anything else.
 
Your 2nd assumption of a stuck amandad process on the client was correct. I've killed the amanda processes and tried again except this time I've included only one filesystem from the tape server and one from the client server - that completed fine. No problems. But when I include all the filesystems on the client machine, I get the same error all over again:

The "amandad busy" means that the server did sent a request while
the client was still busy with processing another request.

That could happen when you have more than one amandaserver and
the amandad on the client is already busy with another server.!
Make sure a client has all his disklist entries in only one server.

Or you could have a stuck amandad client, still handling some request
from the previous test. Kill all the amanda processes on the client,
and try again.
