I have seen the same problems. Like yourself, I am sure that there is no endgame tablebases or other disk access coming into effect. My hashtable size was 256Mb on a 512Mb RAM machine and it was no where near to being an endgame position. I had just put it down to some sort of bug or weakness or the program?! As an aside, I have found, Shredder 5 shows bizarra NPS and "hash used" figures after a significant period of time. Tiger can show a negative position total. Once again, I put it down as a bug.
