This means that if you have more than 8 connections open in parallel any
further connection requests will get reset.  It sounds like that is your
problem.  I would try increasing this (if you have the spare memory) and
see if it helps.  You could confirm if it is the problem by using the
lwIP stats code which will log usage of PCBs among other things, as well
as if you've ever run out of them.
