Hi Jon, sorry I forgot to mention your name in the post and thank you very much for the reply. I think your guess of the machine running out of memory is correct; that's my guess too but I just don't understand why it happened. I can understand the scenario you described but actually I omitted some details in the post to keep it short. I actually disabled the elevator algorithm by substituting in my own elevator_noop_merge function that simply always returns ELEVATOR_NO_MERGE. So each request will only have one buffer_head hanging off it (unless my naive idea of disabling the elevator algorithm didn't work?). It helped to prolong the life of the machine a little more but the machine still died eventually. I'm really confused. Any idea at all? Thank you for your time and sorry again forgetting to mention your name about the book.
