Net::FTP, GET transfers only a part of a file

Hi all,
I'm having a mysterious problem with my script. I'm using
Net::FTP to transfer files from a remote server and only a
part of the file is transferred (2080 bytes vs. 12000 bytes).
After that I try to issue a PWD command which hangs in the
select, waiting for response which never arrives. The reason
for this is that the servers TCP window is full because GET
didn't read all available data from the FTP-DATA channel,
thus I end up in a deadlock, where my script waits for a
response and the server waits that the client would read
some data and make space into the TCP window.
Why GET reads only a part of the file? After the first
read data packet, GET returns OK and my script continues,
and eventually hangs waiting for the response of PWD.
Net::FTP version is 2.72
My perl is:
