Description of problem:
I spacewalk-repo-sync'd fedora-11-i386 (17510 pkgs, os+updates). This went pretty smooth and I was also able to interrupt (ctrl+c) it now and then to continue the sync later. Works perfect!

But then, just when the task is about to finish, I get errors with the last some pkgs. I have two spacewalk set up and they both run that task. One failed with the last 6 pkgs, the other with the last 5. The last batch (i.e. the number of pkgs still to sync since the last interrupt-and-go-again) was once <2k and once >13k.

In both cases, running spacewalk-repo-sync with the exact same parameters had no problem to sync the remaining 5-6 pkgs. Oh, and it's not been the same pkgs that failed.

Version-Release number of selected component (if applicable):
spacewalk-backend-tools-0.6.30-1.el5.noarch

How reproducible:
Twice so far

Steps to Reproduce:
1. spacewalk-repo-sync a yum repo that has F11 os+updates merged into one (as of yesterday 17510 pkgs)
2. wait some hours (except you have lots of CPU cores/power and RAM)
  
Actual results:
InvalidPackageError

Expected results:
no errors at all
