LOC exceptions filling Debug log to the tune of 3-6GB per day

We're seeing a large amount of these exceptions in the debug log, one every couple of seconds. I searched the existing Cru/Fisheye issues and couldn't seem to find anything related.

The Deployables folder no longer exists at HEAD, but we see this for other files in branches and Trunks that still exist. This doesn't seem dependent on users accessing the application, it just seems to be constantly writing out.
