Unless I'm mistaken, this generally means that your process table is full.
A reboot should be able to fix it; you might want to kick off a cron job
to send you a weekly listing of "ps -auxww" just to see what's going on
from then on. If it still occurs after a reboot, I concur with others who
have worries about your physical memory going on its way out. (Note:
while a kernel recompile under 2.2.x, or a tweak to /proc under 2.4.x,
would be able to increase your process table, that would likely be
treating the symptom, and not the cause. You should really try to see
what went haywire and filled up the table.)

P.P.S. This is why I always compile my kernels with process accounting
enabled -- it's cool to be able to see what was doing what. While you
don't get full command lines, you *do* get to see which command, and a
timestamp.
