PANIC. The BP6 is a pretty solid 440BX based board, so I doubt that is the culprit. FreeBSD has no problems with this board or the PIII you're using on it. It's the memory. > 2) Server is booted with all DIMMS, on a KA7. PANIC. The KA7 is a VIA KX133 based board. I have never found VIA chipsets to be reliable.

You can see the > uptimes for the documented panics at the bottom of the JPEGs. I hate to tell you this, but this is most certainly a memory problem. Get some memory that has been tested and approved by your motherboard manufacturer for that board, and to be double-sure, make it ECC memory and then enable ECC in the motherboard's BIOS. If you STILL have problems after that, then you can start blaming the problem on something else. The ONLY other time I have had problems like this is when overclocking the processor. You aren't overclocking those processors are you? -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
