Hi Marcin Juszkiewiczm,

You mean that you are building the kernel on the filesystem over usb storage, and at the same time
you are controlling from remote, then oom happened?

If so, could you disconnect ethernet connection(usbnet) to build kernel on usb storage and
see if the oom can happen?


thanks,

  Strange out of memory on pandaboard

  A GCC trunk bootstrap fails with:

  Looking at top at the time of failure:

  Mem:    681844k total,   368152k used,   313692k free,     6076k buffers
  Swap:        0k total,        0k used,        0k free,   240456k cached

  /home is mounted over NFS, swap is commented out, make bootstrap after
  a clean boot, /etc/rc.local has:

  sysctl -w vm.overcommit_memory=2
  echo 0 > /proc/sys/kernel/randomize_va_space

  In a different situation, with mem=768M in a previous test I got various issues reported in /var/log/messages

  rsalveti asked me to open a report.
