Or add more swap.  In this case, although the memory needs to be
allocated, but it is not under active use so swap would work well.

On the other hand, on a 32-bit system, depending on the policy for
expanding/copying the receive buffer, we might be hitting the 3GB(?)
virtual memory limit.

'sendfile_max_chunk' might be the right knob for this.
