This machine is a dedicated NFS server. Everything on the system is "default": no custom kernel, no custom filesystem options, no tweaking. Earlier today I ran "rm -R" on a directory containing millions of files in its various subdirectories. Within a minute or so the machine hung, NFS stopped working, and I had a posse of angry computational linguists knocking on my door. I ^Ced to no avail. So I tried opening another ssh session--no luck. I pinged. I nmapped. Nothing. I jumped up and ran to the server room. By the time I got there it was back up (whew!) but it had rebooted itself in the process (d'oh!). The directory, or most of it, was still there. I tried not to think too much about it. I went to the annual holiday party. I had a few adult beverages. I woke up a little while ago with a mysterious and slightly painful bump on my forehead and something scribbled on my dining room table with a green Sharpie*. It seemed as good a time as any to try deleting that directory again. So I did. With identical results. The machine hung for a few minutes and then spontenously rebooted. The total size of the directory is ~100G. It lives on a 1T UFS2+S partition of a 7x200G hardware RAID 5 array, which itself lives in a 16x200G ATA-to-SCSI cabinet. The directory contains millions of tiny files collected by a "website harvesting" project. Any thoughts as to why this might be happening? :Fuzz -- Jason M.

And Sharpies do resemble dry erase markers.
