TCP wrappers uses stdio.  stdio has a limitation on the number of open
files that it supports due to the layout of the FILE structure that's
smaller than the limit the system supports.  This is an ABI problem on
several platforms (Linux isn't the only one that had this problem) which
is generally fixed as part of the 64-bit architecture change.
