Programming

You're not calling wait() anywhere, so you may be generating lots of zombie processes -- processes that have completed but haven't been waited for.

You may wish to keep a thread around that does nothing but call wait() in a loop to handle them. You could also catch the SIGCHLD signal but this is subject to problems.[COLOR="#738fbf"]

Code:

int main(void)
{
  initialize();
  while (FCGI_Accept() >= 0)  
  {
		  pid_t pid = fork();
		  if(pid < 0)
		  {
		    exit(1);
		  }
		  else if(pid == 0)
		  {
		    //do things
				  continue;
		  }
		  bstring s = bfromcstr("Content-type: text/html\n\n");

    bcatcstr(s, "hellow");
    printf("%s",s->data);
  }
  return EXIT_SUCCESS;
}

You are not making your child processes quit! That continue should be an exit, unless you want growing swarms of copies of your process all waiting on while (FCGI_Accept() >= 0).
