[-- Attachment #1 --] Hello, This problem has been going on for at least the past 2 years. I've had the exact same issue with rtorrent locking up or restarting machines running FreeBSD, regardless of the hardware used. I did not have any sort of firewall installed (neither pf, or ipfw). If I loaded up rtorrent and had a number of torrents open the machines would lock up or restart. It was reproducible at the time, but I could never get anyone to admit there was a bug and I'm unable to find the initial posting.
