Is that an itunes file or mp4 type?

Nope, pure voice only live streaming.

After further investigation, it begins to crash just after a client
disconnection which seems to have been 'badly' disconnected: the
shared objects this client has been connected to haven't been notified
of the client disconnection.

when one of the client disconnection wasn't notified

Related ticket : http://www.red5.org/ticket/716

As it is written in the ticket, this bug has been introduced with
r4015.

I was wondering if it was a possible case to have a null stream in
PlayEngine.java: playLive() or not
IBroadcastStream stream = (IBroadcastStream)
((IBroadcastScope)msgIn).getAttribute(IBroadcastScope.STREAM_ATTRIBUTE);

.. and if my shared object problems were the cause or the consequences

[Nicolas Leonard]

Any suggestion ? ... I'm definitely not familiar with the red5 code
