Random failures under load

Hello,

Whenever my system is under load, random things will throw errors. For example when compiling large projects, gcc will sometimes crash. I suspect it is hardware related but have no idea how to narrow it down - what would be the best way to diagnose what is happening?

Re: Random failures under load

I find a good way is to have

journalctl -f

Running in a seperate terminal or tmux pane
And keep an eye on the output. Of course you could also
Check logs.  Good luck.

Re: Random failures under load

Thanks, don't know why I didn't think of that at the time. There were some errors:

kernel: mce: [Hardware Error]: CPU 1: Machine Check: 0 Bank 0: 9000004000010005
kernel: mce: [Hardware Error]: TSC 20d45109578e
kernel: mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1496779279 SOCKET 0 APIC 2 microcode 1c

So a cpu error then, anything I can do besides buying new hardware?

Re: Random failures under load

I cant help much with the error, do you have the intel-ucode (microcode) pkg installed and  appended in bootloaders config ?
[edit] not in append but in the initrd, looks like this in syslinux
    INITRD ../intel-ucode.img,../initramfs-linux.img
