apt-mirror size mismatch

[jledhead]

I recently setup a debian mirror so I can update our servers. In my tests it seemed to work like a champ. I am using apt-mirror and lenny, and mirroring i386 and amd64 and was able to install new 32 and 64 systems from this mirror. updating seemed fine as well. Now all the sudden I am getting size mismatch when trying to download archives. I get this if I am on the mirror server and trying to install from itself. I can't seem to find anyone else having similar problems.
here is an example error

Failed to fetch http://cdc133asv/security/pool/updates/main/k/krb5/krb5-user_1.6.dfsg.4~beta1-5lenny6_amd64.deb  Size mismatch

any help is appreciated.

let me solve my own question. apparently when I tried to test updating the mirror, it corrupted some packages. running the sync over night has corrected the problem.

Thanks.
