Hello, this is just to report back that disabling hyper-threading in the BIOS made the problem go away completely. I'm sorry I didn't generate a core dump but because I installed four swap partitions each with half the size of the RAM and the handbook says I needed one swap partition with at least the same size, and I don't have the time to fiddle with partitions now.

Thanks for the help,

Cristóvão

I've disabled SMP with the kern.smp.disabled=1 sysctl and I'll see what happens next. Strangely though the kernel seems to think the system has only one cpu despite it being hyperthreaded:


You want to turn HT off in the BIOS. The scheduler will not make use of it, and in fact will most likely hurt performance.
