Subject1.3.86 - Stability under high loads: *GOOD*
So I get home from school and find my computer trashing *big time*.

I type 'uptime' and find these wonderful values:

12:24pm up 14:02, 2 users, load average: 26.43, 37.54, 38.97

I gasp for air, regain my senses, and find the following values using ps:

USER PID %CPU %MEM SIZE RSS TTY STAT START TIME COMMAND
root 69 0.0 2.2 820 156 ? S 01:39 16:44 /usr/sbin/syslogd
[...]
root 1609 0.0 0.0 1112 0 a3 SW 08:34 0:07 (ppp-on-dialer)
root 12293 0.1 0.5 780 36 a3 S 12:26 0:00 chat -v TIMEOUT
[above two lines about 130x]

What happened was that I had a cron job to collect my mail at 8:30am, but
the host was down, so diald kept spawning new dialers. I had over 300
processes *running* (-not- idle!).

I've since cleaned-up the script so that this *won't* happen again, but it
sure shows that stability is quite good under high loads. Most other
OS's (and I'm not going to mention any names here!) would probably grind to
a halt with sysloads of 30+ for 5 hours straight.
