problems with windows version of mapserver + postgis

[Miguel Ángel Esbri]

Hi,

I have installed the latest MapServer for Windows - MS4W (v. 4.6.1) and 
have configured the WFS server to retrieve the data from a PostGIS 
database. When I make a POST request for some feature  it takes a very 
long time to send a response (about 5 minutes) and I don't even receive 
the full GML file (it should be about 3MB of GML and I only get 700KB).

I have tried the same request using the linux version (4.6.1) and it 
works correctly.

does anybody know if this is a bug or what can I do to fix this?
