Greetings,
I have a Dell PowerEdge 2650 with one 2.8G Xeon CPU and 2G RAM running
5.1-RELEASE. 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?

*In all fairness to myself, the surface of my dining room table does
resemble markerboard. And Sharpies do resemble dry erase markers.
