java.net.SocketException: No buffer space available

Hi,

I was trying to fetch DMOZ open directory using using the exact
example in the nutch tutorial website. So did the following steps:

mkdir db
mkdir segments
bin/nutch admin db -create
bin/nutch inject db -dmozfile ../nutch-0.7.1/content.rdf.u8 -subset 3000
bin/nutch generate db segments
s1=`ls -d segments/2* | tail -1`
echo $s1
bin/nutch fetch -showThreadID -noParsing -threads 50 $s1
bin/nutch updatedb db $s1

It starts fetching the pages, but after couple hundred pages it starts
giving me this exception:

"java.net.SocketException: No buffer space available"

Do you have any idea why this might happen? I know it is running out
of availabe buffer for new socket, but why the old socket are not
closed? Even if a fetch fails its socket should be closed and the its
buffer should get freed!

I tried both 0.7 and 0.7.1.
On example of the given Exception is like this:

051018 153727 28 fetching http://perso.wanadoo.es/largo/
