[Nelug] Stable server starts rebooting

[Douglas Nisbet]

I'm quite busy at the moment so I'm not sure how or when I'll start 
investigating this. I need to give it a bit of thought though.

nick is my dual processor PIII mail server/backup machine. nick lives in 
the loft with no side panels to keep him cool. Normally up for months 
and months at a time, but I've only just noticed I've been getting 
reboots. They seem to have started this month, with THREE this morning, 
and one  a few days ago.

I've got a bad feeling about this. Perhaps a hardware failure saying hello.

I'm thinking of running a script to take a system snapshot so that I 
have a 'ps' around the time of the crash. I don't have the time or 
energy to look into it right now but if anyone has any hints on how to 
get a snapshot of what was happening in a linux box at crashtime I'd be 
interested.

It's normally a very, very well behaved machine. Running Debian Stable.
