Each socket needs a file descriptor. There are two things you need to
configure:

CYGPKG_IO_NFILE
CYGNUM_FILEIO_NFD

By default these are 16, so you have a maximum of 16 open sockets and
files.

Both stacks come from the Unix world, so the stacks themselves should
have no practical limit. Memory is probably you limitation.

Can you estimate the memory footprint required by each open socket/file?
