cached memory keeps growing slowly, and free is going down same way,
after putting ~300MB ftp data (from 8250 board to another host), VM
starts killing some applications

same situation is with latest linuxppc_2_4_devel kernel from denx.de,
but there is additional information from kernel

<5>__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
<5>__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
<5>__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
<5>__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
<5>__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
<4>VM: killing process sshd

what's wrong ???
