It was working all great. Except, when I tried to call the same C-Port [luajit] code from erlang-diameter server. Since the requests were high, but not very high (approx 10K per second), the code fails with stack overflow on c side.

I'm now wondering how to handle this size of requests from the c port. Any help or direction is appreciated. Please let me know if my question is not clear. I'm attaching the code to access lua that works with single instance of c-port process.
