memtest86+ would definitely detect a DIMM slot being bad, so running it for 25 hours successfully means the DIMM and the DIMM slot is likely fine. > I started up and started downloading a backup of over 5K emails.

All of the functions listed in the backtrace show UFS/FFS problems and filesystem metadata issues of some kind. Booting the machine in single-user mode and run "fsck -y". I'm betting you'll find errors. If not, then it's probably a kernel bug -- see below, however. I doubt you're going to get much support on this, since you're running FreeBSD 5.5, which is no longer supported. Believe me: you will get continual push-back from the rest of the FreeBSD developers asking for support on 5.5. The RELENG_6 series is on its way out as well, so you should consider installing RELENG_7 (specifically 7.1-BETA at this point). -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
