I guess it is possible, if not even likely, that the shutdown was temperature-related. I'll investigate the fan filters and clean some dust if they're clogged. The fact that the machine has very small load (0.1 - 0.2) most of the time and that the disk activity at the time of shutdown was not intensive leads me to believe that this isn't the case, but who knows? > UPS drivers can shut the system down, but you seemed to have ruled > that out? The UPS is present, but I never set up and configured anything (no snmp or any other agents) that would give the UPS the permission to shutdown the machine and besides there are more machines on the same UPS that continued to work just fine, so I guess that UPS is ruled out, yes. > It could be triggered by the acpi_thermal driver.

This is actually what I was looking for, even if it turns out it is not the solution: a pointer to a useful port plus pointer to reading the temperatures with sysctl. That kind of things makes the -questions an invaluable resource. That remark led me to discover the following: - kldstat shows acpi.ko loaded - sysctl has no acpi thermal variables whatsoever! which further led me to check for acpi thermal variables on another FreeBSD 6.2 (non-Dell) server and sure they were there. So it seems that acpi thermal is not working (is perhaps "blacklisted", a term I noticed in the man page) on Dell Poweredge (in this case PE 1750 as well as PE 750) servers. Anyone can verify this? > If the system both shutdown *and* rebooted, I had the same inexplicable thing > happen to me many times. Actually, a small correction - the server shut down and stayed that way until I turned it back on a couple of hours later. After that, the server booted just fine and is up right now. It even survived 3 AM tonight without shutting down.
