I meant to type www.memtest86.com memtest from ports isn't quite the same thing --- memtest86 is a standalone program that you boot your whole machine into from floppy or cdrom. Works with any i386 hardware irrespective of operating sytem. > This reminds me, when I did a buildworld, the make exited signal 11 > and the machine panic'ed.

It's usually attributed to "bad memory" but as you've been able to test your memory using a hardware tester (which is the only way to get 100% certainty on the answers) you should start to look elsewhere. At this point I'd be peering suspiciously at the CPU. Faults in the on-board cache memory will have the same effects as in the system RAM. However, before swapping out your processor, double check that it's being kept properly cool. Aside from the obvious "are the fans working", make sure that the heatsink is correctly mounted and that the thermal pad or thermal grease between it and the actual chip are providing good contact. > At this point, though, I want to investigate this.

CFLAGS= -O -g in /etc/make.conf When you do a port build and install, the installed binaries will be stripped, but an unstripped version should be available in the work directory in the ports tree which you can use for debugging.
