I don't know if it's the same issue you're facing, but as I was trying
to track down a NSE looping issue I was seeing last week, I noticed that
a few of the scripts that I wrote don't properly close sockets on error
paths.  This was leading to resource starvation with available sockets,
which the garbage collection fix that Stoiko and Diman checked in
corrected (at least in my testing).  Anyway, here's a patch that
corrects that behavior in those scripts.  Maybe it will help.
