Update:
We moved the backuppc server to the same room as the client server and
on the same switch. The backup still failed, but got alot further. The
error is the same as last time:
Read EOF:
Tried again: got 0 bytes
Child is aborting
Can't write 33792 bytes to socket
Sending csums, cnt = 250243, phase = 1
Done: 26416 files, 31698685174 bytes
Got fatal error during xfer (aborted by signal=PIPE)
Backup aborted by user signal
Saving this as a partial backup
So I ran the exact command as the backuppc user that it uses according
to the log file and ran it manually. Then I straced the pid on the
client machine and got this:
select(1, [0], [], NULL, {45, 57000}) = 0 (Timeout)

It still appears the problem is on the remote server since it is
exiting. The client server is a Dell poweredge so I would hope it
wasn't hardware related. Anything else I can check before I give it a
swift kick in the pants?

I did some more testing watching top and such on both backuppc
server and the client. Both had plenty of memory and such. The
thing we are thinking is possibly the cable or switch between the
two. Tomorrow we plan to relocate the backuppc server from it's
current location and plug it directly in via crossover cable to
the server. That will eliminate the networking gear all except the
network intercafe cards.
Thanks for the input.

Looks like something is wrong on the target side, dropping the
connection. File system problems? Out of memory? Are both
machines on
the same LAN or could there be a problem with networking equipment
between them?

This doesn't tell you anything except that the other end died.

Backuppc doesn't use the rsync binary on the server side - it
has its
own implementation in perl. But it looks like things started
OK and
then either the remote side quite or the network connection
had a problem.
