For now, this goes in the FYI category: I have a student that's implemented a simple error-recording database.  We've now installed it on our lab machines, and you can see some early results here:

The goal of the project is to allow students & others to provide helpful hints that will guide people toward solutions to their problems.  As you can see, this early version has way-too-coarse categories: we're looking into using measures of string similarity to group similar-looking error messages.
