When running:

  strace -s 234 -o t wget -O /dev/null \
     http://hydra.gnu.org/nar/6rz8gpy7ax6334ihw87zyaxyibz96hc3-texlive-2014-data

we see:

  write(5, "GET /nar/6rz8gpy7ax6334ihw87zyaxyibz96hc3-texlive-2014-data

  read(5, "76634478\r\n", 10)             = 10

This is telling us that this is chunked encoding, and that the first
chunk’s size is #x76634478 B = 1986217080 B = 1.9 GiB.  Ouch!

You could buy more RAM.  ;-)  We’ll fix <http://bugs.gnu.org/19939>, see
whether we can backport it in Guix, and also see if we can ask nginx to
provide reasonable chunks.

Thanks,
Ludo’.
