Subject: Re: [ale] Fast NFS

I think it may be related to the ARM board.  It has only 32mb of mem and
that is not much when compiling glibc.

Here is kernel log:

__alloc_pages: 0-order allocation failed (gfp=0x92/0)
__alloc_pages: 0-order allocation failed (gfp=0x92/0)
__alloc_pages: 0-order allocation failed (gfp=0x92/0)
__alloc_pages: 0-order allocation failed (gfp=0x92/0)
__alloc_pages: 0-order allocation failed (gfp=0x92/0)

Which tells me we are running out of memeory.
