After some research and troubleshooting, it seems the issue was definitily related to the KB Mentioned in above posts.
It appears that in attempting to fix a timestamp issue on packages in a previous rollup (R11?), it reversed the effect or created a bug in R14 and caused a handful of our packages to redownload. We let the downloads finish and at this point it seems to be back to normal and under control.
I would recommend to anyone that might be planning to upgrade to R13 or R14, be sure you have some blockouts in place on your package servers that reside at important sites or locations, just in case this issue occurs and slams your network during production hours.
Thanks,
Eric
