The limit that as noted by Symantec in 7.0 is 1,024KB. I always took that into account in 7.0 and we never had a problem. That however is not the problem in this case. Some of these files are as small as 10k. No, I think there is something more sinister going on here, like a major bug.
We are not doing anything process wise that we were not doing in 7.0.
