Yep. If you have a program that tries to fork() and then tries to use NNG in the child (without calling exec) then it fails. There are a lot of problems with fork() and threads - too many for NNG to attempt to solve. (Fork and pthreads are basically inherently incompatible.)

I'm going to close this, because it's a well known - and documented - issue. You can't use fork() (unless you are going to exec immediately afterwards in the child) with NNG.
