I was deleting a directory and the system crashed. It spat out a message along the lines of "ufs_dirrem bad link count 2 on parent". I thought it was so strange I repeated the process several times, and each time it crashed. Is this behavior EXPECTED? I can't for the life of me think of a time or operating system I've run where I've ever had a system crash on me from doing something as basic as deleting a file. Anyway I couldn't boot into single user for some reason so I booted from a USB image, ran fsck, and then everything was fine.
