Mondarchive crashes with "buffer overflow detected" while building catalog

[melevittfl@…]

Hi,

I'm trying to use mondoarchive on a Fedora Core 5 system to backup the system to an ext2 partition on an external usb hard disk.

While creating the catalog, Mondoarchive gets to about 93% done and then crashes. Output of stack trace and log to follow:

NB: Mondo logs almost everything, so don't panic if you see some error messages. Please read them carefully before you decide to break out in a cold sweat. Despite (or perhaps because of) the wealth of messages. some users are inclined to stop reading this log. If Mondo stopped for some reason, chances are it's detailed here. More than likely there's a message at the very end of this log that will tell you what is wrong. Please read it! -Devteam
