Strange behaviour of udpsrc

Hi all,

I have a simple pipeline that listens on a port and redirects an audio
stream to the speakers.

The input stream is really variable since there are different "talkers" that
connect to the UDP source, but never in the same time.

The problem is that sometimes, in a "what-it-seems" random way, the pipeline
hangs out and stops sending out the incoming stream, the only way to let it
start again to stream is to kill the process and restart it.

This is the pipeline:
gst-launch-1.0 udpsrc port=5555 !
"application/x-rtp,media=audio,clock-rate=44100,width=16,height=16,encoding-name=L16,encoding-params=1,channels-1,payload=11"
! queue ! rtpL16depay ! audioconvert ! autoaudiosink

Any idea about what can cause this issue? Is there a good way to redirect a
debug stream to a text file and analize it after the freeze?

Thank you for help
Walter
