question about apache bench

Hi there,

I'm trying to understand something : I'm using the apache bench program
(ab) to benchmark some apache modules.

It produces the following output :
----------------------------------------------------------------------

What means a failed request with a "Length" error ? Does this mean only
that some documents have different sizes ?

If you have any information about this, please let me know.

Thank you,
