Hi Marcin Juszkiewicz,

If out of memory always happened when you build something over a NFS, it is very possibly caused by usbnet,
which seems to be shown from #28.

The issue has been discussed in maillist recently:

       http://marc.info/?t=130406641000006&r=1&w=2
       http://marc.info/?t=130471082300010&r=1&w=2

but still have not a good solution to fix this, I will try to figure out
a patch to address the issue.

thanks,
Ming Lei

  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
  copy here: wget http://guerby.org/ftp/messages-pandaboard

  rsalveti asked me to open a report.
