There are better ways to hunt down spinning processes. A simple method is
to note that it's eating time. Prob is that Netscape also does this when
being used :(.
Doesn't it lose assocication with a tty when this happens?
sh-2.01$ uptime
1:50am up 259 days, 2:23, 34 users, load average: 0.00, 0.01, 0.00
sh-2.01$ ps aux | tr : ' ' | sort +10 -n | tail -5
root 435 0.0 0.3 3004 816 p2 S 02 03 22 01 xterm
lufthans 347 0.0 1.1 7572 2928 ? S 01 59 23 44 kwm
root 2683 0.0 0.2 2884 612 ? S 01 50 90 31 xterm
root 30178 1.2 0.1 1668 452 p3 S Oct 7 182 47 ssh spliff
root 176 99.9 9.6 36824 24988 ? S 01 55 967 01 /usr/bin/X11/X
X has been up since I booted, so almost 300 days. It still hasn't broken
1000 minutes.
If it's a desktop you can probably trigger on anything hitting more than
100 minutes. If it's a server, maybe try 100, but be prepared to move to
500 or 1000 for the services the machine is providing.
If you've got spinning processes, check them by hand. You can probably
just kill Netscapes. If it's a service like nfs or apache you probably
want to investigate why it's spinning, not just ignore the prob.
