I've been running into about the same problem for quite some time now, my box
crashes while running some periodic job. Some find never end, they stack up,
and when my coworkers usually do a killall -9 find, the box is unresponsive
from network, and after a reboot, it says 2 or 3 times 'kern.maxpipekva
exceeded...' in syslog.

I'd try to see what makes it block next time it happens.
