I am getting alot of theese errors in my event log on my dnn 4.5 site.

I upgraded the site from 4.4.1. It does not effect the users experience. I am open for suggestions what this means. I have gone into the search admin and re-indexed the site.

You can view the site at http://www.packtx.org

Here is the error:

DNN used to throw that error when the total portal size hit 2GB and has since been fixed (I think in the early 4.0 versions). However a lot of modules still used the old process and will throw the error (in this case it looks like the Reports module). I'd check to make sure you've got the latest version of the Reports module and if you do then post the problem in that forum.
