[rdiff-backup-users] too many current_mirror incs! happening too often!

[Micah Anderson]

I've got a set of remote machines that seem to keep failing with the
below trace. To solve it, I go to the backup machine, I look and I
typically find 2 or 3 current_mirror* files, so I remove the newest two
and start things again. However, a few backups later, same problem. The
backup typically would finish in a couple hours, and the next one would
be run much later, so this doesn't seem to be an overlapping backup
problem. 

This is with rdiff-backup 1.2.5 Debian Lenny.

Perhaps this is just a residual trace from a previous failure and I
should be looking for the original traceback that caused the second
current_mirror inc to be created?
