Hi.
I've had a box running as a server for a few years.
It's been offline for a week for so because i relocated.
Now it's up again, but for some reason, it becomes nonresponsive from
time to time.
I find nothing in the logs (the ones I've looked in).
In syslog, I find only that there are no 'marks' after it dies:
Apr 2 19:31:27 localhost -- MARK --
Apr 2 19:51:27 localhost -- MARK --
Apr 2 20:11:27 localhost -- MARK --
Apr 5 10:16:05 localhost syslogd 1.4.1#18: restart.

daemon.log, messages, and syslog also have nothing that points out to me
what happened.

I attached a screen and a keyboard to the box. After a while, the screen
blanks, but comes to life when I touch a key (standard behaviour) - but
when it stops responding to requests (mail and http), it also does not
come to life on my keypresses.

Any ideas how I can find out what makes it die?

Thanks,
