It got caught in a panic - reboot loop with the following message: panic: vm_page_free: invalid wire count It seems to coincide with file-system check activity. [The file system claimed to have been beat up around the same time] I tried to reinstall assuming the file system was toast, but got the same message when the installer tried to create the file-systems. When I looked at the source code that was panicing it seemed that someone was trying to free a page that someone else was still referencing? Does anyone have any idea what kind of error this is? I'm guessing that its either a fault with the RAM or the processor chip since the machine worked fine for a couple of months before it died. I tried swapping the two memory modules, but it didn't help, and I don't have any spare machines to canabalize for other substitutions Machine was a P5-166 with 32M RAM --- thanks, G
