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:

Why does the server sent a request, while the client believes it is
still handling a previous one? There are also duplicate packets.
Is there an ACK that got lost?
Is there a large number of disks for that host?
Maybe the reply UDP packet somehow did not get to the server completely.
Maybe because you hit a limit or bug in large UDP packet handling.
The packet that is sent to the server, is printed in the same amandad
debug file.
Using tcpdump/snoop/ethereal you may watch the traffic on the
client and host for port 10080, and compare the traces to verify that
what is sent by the client, is also received at the server.
What OS is the client? Server? I've even heard about network devices
inbetween that mangled large UDP packets beyond recognition.
You may compare a amandad.debug file from a succeeded run with an
error run and see where it breaks.
