Subject: questions about Fatal Trap 12
I have received a kernel Trap 12 error several times now and am trying to
figure it out.
the error occurred today, and the previous time was about two weeks ago.
last time I had to run fsck manually if that proves anything.
uname -a gives the following:
FreeBSD wserver.********.com 7.0-RELEASE-p3 FreeBSD 7.0-RELEASE-p3 #0: Wed
17 13:30:46 MDT 2008 r...@wserver.*********.com:/usr/obj/usr/src/sys/MOD
Google returns results mostly for versions 4.x and 5.x, but it suggest 2
test ram, and kernel panic troubleshooting.
Is there a way to test the ram without removing it from the machine and
the machine functioning. I've used memtest 86 before, but obviously the
machine has to be offline for this test.
However, I'm a little unsure of the instructions in the handbook on
troubleshooting. namely, it talks about using the nm command, put I can't
figure out the data file to give it as an argument, and second I'm unsure
using a debugging Kernel on a production server. I have heard that It will
significantly slow down a machine.
Any help or suggestions would be greatly appreciated.
I have had a few of the Trap 12 errors over the last 10 years of using
FreeBSD. From memory, mine where due to faulty motherboard/CPU. I just
moved the hard drive to another PC, and all was ok.
The last time I received the error, was when I tried recompiling world. I
put it down to CPU heat, as it was running a LOT harder than normal day to
day use. This was on a server that had been in place for two years running
with out problem!
