Hello, 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 Sep 17 13:30:46 MDT 2008 root@wserver.*********.com:/usr/obj/usr/src/sys/MOD amd64 Google returns results mostly for versions 4.x and 5.x, but it suggest 2 main things: test ram, and kernel panic troubleshooting. (http://www.freebsd.org/doc/en/books/faq/advanced.html#KERNEL-PANIC- TROUBLESHOOTING) Is there a way to test the ram without removing it from the machine and leave 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 about 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. Ray
