[Samba] smbd panic - tdb_reopen: file dev/inode has changed!

Hi folks,

# uname -srvo
Linux 2.6.18-194.el5xen #1 SMP Tue Mar 16 22:01:26 EDT 2010 GNU/Linux

Version 3.3.8-0.51.el5

I'm trying to run a backup samba server using some custom in-house
scripts which I inherited and am stuck with.  Essentially the primary
server periodically rsyncs a bunch of files over to the backup,
including a collection of the tdb files.  When I try to connect to the
backup server, I get the following smbd panics in the logs:
