Pipes can only hold a limited number of bytes, and your pipe is getting filled.

You have a Deadlock.

Run the parent asynchronously instead of waiting for the child to end, or use qx// to launch the child.

By the way, it's probably not a good idea to use waitpid on a child launched using open. Closing the handle is the appropriate way of reaping the child.

By the way, please put computer text (code, data) in between <c>...</c> tags. It preserves the formatting, escapes characters that need escaping and provides a handy download link.
