Had you just generated a new system (by going through an unexplored JP) in the last 5-day? The most likely thing to have happened is that the corrupt body is brand new. Are there NPR active? If so, they could have generated the system during their explorations.
It might be worth keeping the corrupt DB around in case Steve wants to take a look at it....
