Ubuntu freezes when compiling software

  • 772

I have a Xubunut16.04 install with 16GB RAM and a 20GB enrypted Swap.

When I start a large compilation with

 configure
 make -j

in a terminal, I can see in the panel load monitor

  • all cores go to 100%
  • memory goes up to 100% in about 20secs
  • The Swap display remains at zero. As soon as the memory is a 100%, the whole PC freezes up. I can do nothig via keyboard/mouse. I can not got to another terminal. I can not login via ssh from another PC. The HDD light is on and the disk is spinning.

I can reproduce it every time. I have waited up to 5hrs, but there is no change (it does not revocer). I need to do a hard reset.

I read a lot in the forum and found hints on the Swap and cypttab. From the commands I could check before starting the complilation all is fine.

  • The Swap setup is just the standard default. The UUID of the blkid command and the content of /etc/fstab and etc/cypttab is consistent

  • swap seems to be on

    swapon --show
    NAME..... TYPE.... SIZE USED PRIO
    /dev/sm-0 partition 15.2G 0B ..... -1

Since the PC was Idle USED=0B seems ok. No Idea if PRIO=-1 is OK.

  • cryptsetup seems to beworking cryptsetup status cryptswap1 /dev/nmapper/cryptswap1 is active and is in use [...]

I tried to set the values for vm.min_free_kbyptes and vm.swappiness

sudo nano 
vm.swappiness 40
vm.min_free_kbyptes=240000

This is the syslog section of the crash

What can I do? Is this normal that one can crash an Ubuntu installation that easily? Crash it with user privileges?

swap freeze ram make

  1. I found a way to prevent the system from crashing (see below). But I hope there is another way because the post above means that a simple userland command 'make -j' can crash a whole pc. How can that it be that a safe OS as Linux does not prevent that?

    The system does not crash when I:

    1. compiled from a text console (ctrl-alt-f1)
    2. changed the variable TEMPDIR to a path on disk with
    mkdir /home/username/tmp
export TEMPDIR=home/username/tmp

    Maybe someone can explain why that works.

    [update]: it works but only sort of. When using for example 'make -j4', the system is faster by far, because all this caching, task killing when running with unlimited jobs is omitted. Running with above changes, the system does not crash, but its severely bogged down for other users or in other terminal of the same user.
