reports with large output failing

We have a need to generate data that is creating large reports, and failing.

Ideally, we wish to get "Access Details for Paths" to generate a CSV for a large base of folders/files, across a large period of time.   Even carving the time down to single days, results in timeouts.   Carving it further into sections of folders and by hour, is a tedius process and taking too long.

We have the maximum value set for automatic truncating of results set, but may need to exceed this.  Regardless, its not truncating its simply failing to complete (example last report ran for about 100 hours before failing).

We are running version 5 with RP1

Any suggestions, ideas?  Thanks!
