That'd be the infamous uninterruptible sleep (which shows up as
status D). It also manifests itself on hardware failure and when the
box is thrashing.
I've been cussing a high-traffic box today that had about 30 CGI
scripts in D state. Note I didn't say FastCGI or mod_perl. It also
doesn't have "firefighter" or "sysadmin" in my job description...
