[streaming] What mean this error? "late picture skipped"

[admin at warbox.co.cc]

Hello, im using VLC-nox to stream my webcam over the network. I was 
compiled VLC as follow:

./configure '--enable-v4l' '--enable-v4l2' '--disable-nls' 
'--disable-mozilla' '--disable-dbus' '--disable-dbus-control' 
'--disable-telepathy' '--disable-lua' '--disable-cdda' '--disable-vcd' 
'--disable-dvb' '-disable-libcddb' '-disable-x11' '--disable-glx' 
'--disable-opengl' '--disable-xvideo' '--disable-xvmc' 
'--disable-freetype' '--disable-fontconfig' '--disable-fb' 
'--disable-qt4' '--disable-skins2' '--disable-sdl' '--disable-sdl-image' 
'--disable-notify' '--disable-libgcrypt' '--disable-mad' 
'--enable-avcodec' '--enable-avformat' '--disable-swscale' 
'--disable-postproc' '--disable-a52' '--disable-remoteosd' 
'--disable-live555'

Im using Debian Lenny server (without X) and I had to compile VLC from 
source because from the repository vlc-nox come with no v4l2 support. I 
start streaming with this command line:

cvlc -vvv v4l2:// :vdev=/dev/video0:width=640:height=480 
:input-slave=alsa://hw:0,0 
:sout="#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,ab=8}:duplicate{dst=std{access=http,mux=ts,dst=0.0.0.0:1234}}"

When the stream is started i can connect from client site and able to 
watch the video, but after moment (maybe 10 seconds) the stream stop 
immediately and i can't connect it again.

Whats happen on the server side, the daemon is working but debug massage 
say:

So anyone know what is the problem, and how to fix it?? Seems problem 
with cache, but how to increase the buffer cache???
