Gents/ladies(!), I'm running several SMP systems but am having regular problems with one of them. I'm not sure if this is really a question for the SMP or the questions list, but I'm trying here first. The machines are dual Xeon 2.4GHz .5MB cache with hyperthreading enabled. They are less than 2 weeks old. They have identical kernels, which leads me to believe this is a hardware problem with this particular machine but I'm not too sure. I'm looking for some advice. I've taken the liberty of posting the log when the machine crashes below. I thought that "Fatal trap 12: page fault while in kernel mode" referred to below suggests that something has eaten up the stack. These machines run Exim + named + anti virus software. I consider them lightly loaded. Does anyone have any suggestions, and if I should post this to questions I apologise. Cheers, John.
