I suggest reading through all the posts in the thread, particularly the
recent ones:

<https://sourceware.org/cgi-bin/search.cgi?wm=wrd&form=extended&m=all&s=D&ul=%2Fml%2Fcygwin%2F%25&q=xz%20-9%20%3A%20Cannot%20allocate%20memory>

If you're still having problems, I recommend you update to the most recent
Cygwin DLL if you're not running it already.  If that's still no help, I
point you back to my recommendation about submitting a full problem report
with cygcheck output as described by the link I provided above.
