(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
