Got fatal error during xfer (Child exited prematurely)

I have a backup server which takes backup of other servers and in few days back the backup server started experiencing error and the not able to take back. I think the error log bellow could describe the problem better than me: 2012-09-10 20:05:40 Aborting backup up after signal PIPE 2012-09-10 20:05:44 Got fatal error during xfer (aborted by
