I have 20 clients running on dual Xeon boxes. Every morning, there are 3 to 5 that have stopped in the last 24 hours. No errors, just stopped at the end of a generation. I most cases, I have had to dump the entire work unit and start over with gen 0.

All boxes are W2K Adv server, with dual HT Xeons running 1 client per virtual CPU, from different folders. This has not been a problem until this protein.
