Something as simple as stack overflow might be the issue.  There are some huge arrays on the stack that might be causing issues:

    struct sockaddr_in address;
    int opt = 1;
    int addrlen = sizeof(address);
/    char buffer[2048] = {0};//
//    char response[4096] = {0};/
    const char *file = "/data/client.html";

So it is going to need a stack allocation of something like 8Kb.
