I'm in the process of changing my Amanda tape server from an HP 9000/735 to
an Athaolon 1.2GHZ. I'm using the same HP branded DLT40, and i've upped the
holding disk from 2G to 40G. The clients are the same. I've also upgraded
(almost all) of the clients to 2.4.3N4.

I am having major problems with dumps failing because of "timeouts". What
appears to be happening is that the clients are losing there concretion to the
host in mid dump. I;ve decreased the number of dumpers, and put in network
bandwidth limiting (using Amanda.conf), and I;ve had a couple of nights
where everything went OK. But the whole situation seems awfully "fragile".
Before last nights run, i bumped dumpers back up to 16 from 8, and I had 3
filessystems fail! Some filessystems on the same machines succeed.

I don;t believe i have any specific network issues, as no other network
tasks seem to be having problems. The new tapesever is running FreeBSD 4.7
STABLE.

I'm going nuts here, and am looking for any thoughts on this.

Thanks.
