Let's paraphrase: I think i solved this last time by activating 'INVARIANTS'... Anyway, tried that and yes, it didn't crash in the last few hours, so I guess it works. Without INVARIANTS, it crashed within seconds. On the downside, my Gigabit performance dropped from 99 MB/sec to 80 MB/sec because of INVARIANTS.
