Hello List,

One of my backup clients started failing recently. All other clients are fine.

Using /var/lib/amanda/cwnbackup/amdump.1 from Fri Oct 12 13:13:17 BST 2007
ns5:/etc                        0 driver: (aborted:could not connect to data 
port: Connection timed out)(too many dumper retry)
ns5:/home                       0  2256253k wait for dumping
ns5:/root                       0   152813k dumping        0k (13:44:16)
ns5:/var/lib/amanda/            0 driver: (aborted:could not connect to data 
port: Connection timed out)(too many dumper retry)
ns5:/var/named/chroot/var/named 0 driver: (aborted:could not connect to data 
port: Connection timed out)(too many dumper retry)
ns5:/var/spool/mail/            0 driver: (aborted:could not connect to data 
port: Connection timed out)(too many dumper retry)

Here is the debug log from the client:

[root@ns5 amanda]# cat sendbackup.20071012140610.debug

I've adjusted the dtimeout in amanda.conf but that's not improved the situation.

   record no           # Important! avoid interfering with production runs

Could someone please give me some more pointers for investigation / finger 
poking?

I am in #amanda as robdyke


Thanks,
Rob
