Slackware Linux machine hangs for no apparent reason
I have a dedicated machine collocated at some hosting provider and after a while (14 days or so, but timeframe is not constant) it hangs for no apparent reason. It happened 2 times already. Nothing in the logs (it logs everything), nothing at all.
Before the commission the machine was running for a month without any problems.
The first time it happened the tech guy plugged in monitor and keyboard and could not see anything on the display. Before that machine was not loaded with any traffic, nobody should have actually known it is there (except for some DNS traffic). It took some 20 days of uptime.
The second time it happened was yesterday, after some 15 days of uptime.
I suspect hardware malfunction because I have 2 "identical" (OS & progs, not the hardware) systems running without any problems. It is an HP DL380 G5 machine, the problematic one.
I am asking if any of you could please share some hint on how to analyze/diagnose such a problem?

It could be memory. I had a Slackware box a few years ago that used to crash aperiodically - complete freeze. It turned out to be one of the sticks of RAM was bad. However checking it involved running memtest to diagnose the problem. The RAM was fine when the box was built but degraded over time. The catch was that the crash only happened when the affected memory area was used.
Domain History Search and Webhoster Statistics.
Hoster Stats for over 7M hosters and over 467M domains.
Now with domain hosting history for new gTLDs.
Don't the DL380's have ECC (if enabled)? Also, configure your iLO so you can remote when it crashes to investigate (and check the iLO logs). iLO would probably give you better clues than a keyboard/monitor plugged in.
Also, are both power supplies connected? This could tell you whether one of them is failing to draw enough power (faulty) and causes the whole thing to crash.
