The memory is used in common by the userland applications and the
kernel; if you run short of memory and the kernel needs to allocate some
(which is the case in the network driver), it will fail. This might
explain the sudden halts. Can you try to increase the RAM size (just
temporarily, by borrowing some memory modules from other computer) and
test again ?

What do you mean by "it's better" : do the messages still appear ? Do you
get better throughput ?
