getting diff's every hour on my Cisco 2950

I just recently setup rancid and to start i had it just polling my Cisco
3750's but the other night i added a bunch of my Cisco 2950G switches. For
some reason rancid keeps sending me diff's for all but one of those
switches. These diffs are huge also, just just somthing small changing, in
fact it looks like a full dump of everything (initial run). Anybody know
what might be happening here...

Also i have this error in my logs, i havnt figured out how to correct it but
maybe it's part of the cause...

starting: Sat Nov 26 10:01:48 PST 2005

Trying to get all of the configs.
All routers sucessfully completed.

cvs diff: Diffing .
cvs diff: Diffing configs
cvs commit: Examining .
cvs commit: Examining configs
cvs commit: Up-to-date check failed for `configs/edge-138.14.irv.xxxxxx.xxx'
cvs [commit aborted]: correct above errors first!

ending: Sat Nov 26 10:01:58 PST 2005

I use Subversion as my backend but ran into a simliar situation which
required a database rebuild (when I was running on subversion 1.0 when
it used the godawful bdb backend. God bless fsfs.

Something or someone has mucked with your CVS store. See the FAQ, its
in there.

Q. I keep receiving the same diff for a (or set of) devices, but I know the
data is not changing repeatedly. Why?
A. This is probably a CVS or filesystem permissions problem. Check the log
file from the last run for that group for clues first; it may provide the
exact cause.

Note: It is very important the following be done as the user who normally
runs the rancid collection from cron.

Check the cvs status of the device's file. example:

guelah [2704] cvs status rtr.shrubbery.net
===================================================================
File: yogi.shrubbery.net Status: Up-to-date

Working revision: 1.197 Tue Jul 10 15:41:16 2001
Repository revision: 1.197 /usr/local/rancid/var/CVS/shrubbery/configs/rtr.shrubbery.net,v
Sticky Tag: (none)
Sticky Date: (none)
Sticky Options: (none)

The Status: should be Up-to-date. If the status is "Unknown", then somehow
the file has been created without being cvs add'ed. This should be
corrected by removing that device's entry from the group's router.db file,
run rancid-run, replace the entry in router.db, and run rancid-run again.

If the Status is anything else, someone has most likely been touching the
files manually. Sane state can be achieved by removing the file and running
cvs update <file> to get a fresh copy from the repository.

Check the ownership and permissions of the file and directory and the
directory and file in the cvs repository (<LOCALSTATEDIR>/CVS/). They
should be owned by the user who runs rancid-run from cron. At the very
least, the directory and files should be writable by the rancid user. Group
and world permissions will determined by the umask (default 027), which is
set in <SYSCONFDIR>/rancid.conf. Likely the easiest way to fix the
ownership on the cvs repository is
chown -R <rancid user> <LOCALSTATEDIR>/CVS <LOCALSTATEDIR>/<GROUPS>
