You should probably not use NUMB_IP, NUMB_PORT, NUMB_USER, NUMB_PASS as
copy/pasted from the unit test, those are configuration defines for using the
numb server for testing and makes no sense for you to do that. Use renamed
macros or variables.

Make sure the server isn't running out of allocations, see my answer to question
#4 in here : http://lists.freedesktop.org/archives/nice/2012-October/000659.html
Otherwise, the code looks good, and it does seem to work. If you're sure the
allocations are not full, then a NIC_DEBUG=all log would be helpful in finding
out what's causing it.
