Well this sounds very much like my problem, I do get more life
from the system, though its days are numbered.

I filed under security because I thought it had to do with a
particular tar.bz2 archive causing a DOS condition.

security/36712: tar extraction cause cannot create pipe, too many open files
http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=36712

I'm finding inability to create pipes after disk use. My system is
also a multi-core Opteron, but I've only experienced the problem
after lots of disk access, using a LSI fibre HBA attached to an
external disk enclosure.
