Augment your input filter script with debug statements so you can
trace exactly what it is doing, ie., data read, accumulated length of
data etc etc.

Use apache.log_error() function to do this.

Post your results, analysis and code used.

I still don't believe modifying util.py is the answer, it is more
likely to be something in your input filter not passing everything
back or truncating it.
