Dunno what your hardware configuration is, H.J., but I have a dual PII
running 2.1.122 which is a mail exchanger. I got in to work this morning,
and was in the process of getting mailbombed; the system load rode between
5 and 7, and the box was 70% into it's swap space. It was in this
condition, as far as I can tell from the logs, for about three hours. I
was impressed at how well this machine handled the situation, actually;
there wasn't even much lag at the keyboard. =) Anyhow, here's another
gratuitous "free" report:
