Re: debian lenny sudden restart
Hi I once had a computer with restart problems. It came out that the thermal glue between the processor and the hit sinc was missing.

I don't see anything specific right now but googl'ing for "linux checkpoint restart" comes up with a few links, most prominent is Berkeley Labs Checkpoint/Restart (BLCR): https://ftg.lbl.gov/CheckpointRestart/CheckpointRestart.shtml Another option I heard about, though never tried, is to take VMware snapshot - run your calc in a VMware virtual machine and take a snapshot of the entire VM. Then if it (or its host) crashes for some reason you should be able to restore it to the checkpointed state.

Debian Lenny Xorg X-Server woes (was: Re: debian lenny sudden restart)
Shimon: 1. You may be able to save the long calculation by running it from one of the consoles instead of the X-Server. 2. Check your keyboard configuration. Any Debian Lenny Xorg X-Window expert in Linux-IL: 1. Where to set options so that the Xorg.0.log will be more verbose? (according to man Xorg, the -logverbose option sets the verbosity level) 2. Does the X-Server log runtime information (rather than init-time only) in the same logfile or in another logfile? If in another logfile - where? --- Omer On Sat, 2009-07-18 at 09:58 +0300, Shimon Panfil wrote: > Quoting Omer Zak : > > > On Thu, 2009-07-16 at 18:21 +0300, Shimon Panfil wrote: > >> Hi folks, > >> today my main box running debian lenny made sudden restart.

Hi Shimon, You have a sparsely occurring intermittent -- as a matter of fact so far it's a single event. If the cause was software, it's possible you can find a clue in the logs. If I were in your shoes and there's no clue in the logs, I would just wait until the problem becomes frequent enough to be a bother. But if you want to address the problem right now, I'd suggest corrective maintenance: 1) Feel if the power supply is getting too hot, and replace it if so. 2) Vacuum out all the dust from the inside. 3) Pull off, lubricate (electronics lubricant) and reseat all cables. 4) If your motherboard batter is more than a year old, replace it. 5) Disable (open circuit) your reboot button, and replace your on/off button with a simple, non-lighted doorbell button. I learned #5 the hard way -- the reboot and power switches that come with the case can go intermittent, and not just intermittent open, but intermittently close without pushing. None of the preceding is diagnostic in nature, but given the rarity of the symptom, if the log files don't have something telling, the preceding are probably the best use of your time.
