We have a computer in our lab we use to run simulations and sometimes compiling. It's been working just fine for over 6 months now but during the last week we had it's first 3 crashes(only fixable by hard restarting the machine). I'm not a very experienced linux user so all I tried to do to find out the crash reason was looking into /var/logs without any sucess. So I tracked down which programs were being used when the crash happened and tried to reproduce the crash.
So one of the targets was make which I was running using $make -j 32. After a few runs trying to make the computer crash again I was able to make it crash using $make -j 128 I'm not sure wheter the reason for the crash is make or gcc but I do know it crashes using that command, so I'd like to know if anyone has ever had this problem before and how I can get more information about the crash that could lead me to the exact crash reason.
Everything described here happened over ssh though I don't think that does make a difference.
Machine configuration when the crash happened: Core i7 @ 2.67GHZ 3GB RAM $uname -a Linux groelandia 2.6.28-16-generic #57-Ubuntu SMP Wed Nov 11 09:47:24 UTC 2009 i686 GNU/Linux
Ubuntu version is 9.04(32 bits) (yeah we do also have a 64 bits version installed =p)
If any info is needed or I sent this message to the wrong place just let me know. Thanks in advance, -- Thiago C. Santini
