I sent the message below yesterday. After having read some other seemingly
unrelated messages, I realized that I did change one of the disks on the
client "client.foo.com" from using dump to tar (see dumptypes below). It
was after this change that the entire client started coming back as
"Request timed out". I got this from reading the other messages saying
that backups with tar took an incredibly long time to generate estimates.
I want to use tar so that I can exclude some areas of that disk. Is it
enough to just increase the etimeout for that client? Am I on the right
track? All the logfiles are still included below from the original message.

I've been running Amanda 2.4.2 for several months now. I have a client,
client.foo.com that has stopped responding and here's what I get from the
Amanda report:
FAILURE AND STRANGE DUMP SUMMARY
client.foo. /disk1 lev 0 FAILED [Request to client.foo.com timed out.]
client.foo. /var lev 0 FAILED [Request to client.foo.com timed out.]
client.foo. /usr lev 0 FAILED [Request to client.foo.com timed out.]
client.foo. /home lev 0 FAILED [Request to client.foo.com timed out.]
client.foo. / lev 0 FAILED [Request to client.foo.com timed out.]
Amanda is launched from inetd and I did verify that inetd was
running. Both client and amanda server are connected to switched 100 Mbps
ports so speed isn't necessarily an issue. I also increased the the
timeouts (although ctimeout I just raised from 30 to 60):
etimeout 1200
dtimeout 1800
ctimeout 60
Here is the debug files for client.foo.com:
