Hi,
Just a note: I spotted similar problem using plain Apache on current Debian stable (squeeze) but perhaps you find this information usefull. The problem appears for files longer than 2600 bytes.

Additionaly, the problem did not appear for other means of transferring data (I tried to transfer the file using netcat, successfully).

Also, I tried to mess with offload setting using ethtool, but the result is:
Cannot set device tcp segmentation offload settings: Operation not supported.

I suspect the error is a strange combination of AR8131 NIC and apache using TCP stack (IIRC writev insted of write).

The box I spotted this problem on is a multihomed box. The problem appears only on Atheros interface.
