[rdiff-backup-users] error in long running system

[Iain Dooley]

hi all, i've been running rdiff-backup for about a year and a half with no 
troubles. i use version 1.1.5 on freebsd 6.2R.

yesterday on two of my systems, i got the error below. other systems are 
still running correctly.

i can't find anything meaningful in the messages below, does anyone else 
have any clues? i've checked and keychain/ssh connection is still working 
fine on both systems into the backup server.

cheers
