Re: [gentoo-user] gentoo box "hangs"
2006/10/7, b.n. <[EMAIL PROTECTED]>: If you suspect the memory/mobo, try instead to compile some large package. Often this results in random segmentation faults for gcc. Faulty memory should result in crashes and segfaults and erratic behaviour, apart from freezes. I had had some trouble with my machine crashing in idle until I overclocked the CPU a bit. My machine has never crashed since then. I think that it's a hardware problem, but I got successfully rid of it so it doesn't matter anymore to me yet I think that there _MUST_ be something that just can't be right. -- gentoo-user@gentoo.org mailing list
Re: [gentoo-user] gentoo box "hangs"
My 2e-2 euro: a relatively frequent freeze of the machine can also mean a going-to-fail power supply. It was for my machine in at least two cases. If you have a good power supply to do the experiment, try. It's a cause more often than not. It is expecially true if the logs say nothing and you just see the machine hang after some hours/days. If you suspect the memory/mobo, try instead to compile some large package. Often this results in random segmentation faults for gcc. Faulty memory should result in crashes and segfaults and erratic behaviour, apart from freezes. These are of course no foolproof fingerprints, just hints... M. -- gentoo-user@gentoo.org mailing list

OK, I googled for this and found the script that I was talking about: http://people.redhat.com/dledford/memtest.html HTH. -- Regards, Mick pgpno8l1ofV3u.pgp Description: PGP signature

There's a whole thread (either in this ML or in the forums) as to why memtest is not a foolproof test for your *system* as opposed to a memory module. Try to search around and look in Google too, in case you find it. There's alternative tests to memtest involving running some script (if I remember right). As I said, whichever test you run you need to make sure that it exercises your whole memory system (modules, controllers, swap). Good luck. :) PS. My box would also crash in M$Windoze if the page file was being used (e.g. manipulating large sections of text or pictures), but not at the frequency of it crashing under Gentoo with a heavy emerge and updatedb taking place. -- Regards, Mick pgppbEyVJd3gH.pgp Description: PGP signature

One question I have - did you run memtest86 or something similar at the time? The reason I'm asking - I ran memtest86 on this machine and it showed nothing. I'm not entirely sure how much I can trust memtest. -- gentoo-user@gentoo.org mailing list

Last time I experienced something like this was on a desktop which had incompatible memory modules fitted. Trial and error resulted in me removing all but one module and the crashes miraculously stopped! Knoppix alone would not cause any crashes whatsoever, but as soon as updatedb and an emerge were to take place simultaneously, the system would crash. In particular, it would usually crash when the memory of the modules was about to be exhausted and the system was going to start writing on the swap partition. It wouldn't happen every single time, but towards the end it was happening every time I booted the darn thing up. I hope this helps. -- Regards, Mick pgp7Bmuya7j0X.pgp Description: PGP signature
