I recently upgraded an amd64 machine to 7.1-RELEASE, and started getting a bunch of these at a pretty high frequency (a few hours to a day apart): http://acm.poly.edu/~spawk/IMG00033.jpg The "current process" is always httpd. They're particularly annoying because the machine doesn't actually ever reboot, requiring manual intervention. Reverting the kernel back to 7.0 makes the panic go away, and the machine had been happily running 7.0 for about a year beforehand. I realize that the photo hardly contains any useful debugging information, but I was hoping it might look familiar to someone. If not, I guess I'll come back with a backtrace. -Boris
