Re: Debugging segmentation faults

You're using Python on a web server to do something complicated. You must suffer. Are you trying to fork off a subprocess in a multithreaded program? That's unlikely to work. The sematics differ from OS to OS (Solaris forks all the threads, most other operating systems don't; most UNIX-
