Here's an application of a problem-solving strategy I've found to be occasionally helpful

  1. Consult perldoc perldiag if you don't understand the error message
  2. Work out why you're getting the error message (if it isn't obvious) from the information thus gleaned.
  3. Follow up on any suggestions you can find in the docs.

Interesting how this question came up right after one4k4's concerning a similar issue; long story short, your whole script is a subroutine when you run it under Apache::Registry. 'Course, you're getting it because you have a nested sub the way you've coded it anyhow. But back to the strategy outlined above =>

From perldoc perldiag the solution to the "won't stay shared" issue is: 

This problem can usually be solved by making the inner
              subroutine anonymous, using the sub {} syntax.

Another approach would be to move the read_size subroutine's declaration outside of the block.

These are purely structural solutions; I'm not even sure you need to be doing what you're trying to do here (read is built to handle the issue of when you try to read a larger chunk than what's left in the file).
