I'm just pressing the 'Esc' key on the video window. 

Also, once the issue appear, no client can't connect anymore, even 65 seconds 
later. I have to restart the software (so the RTSP server) to make the issue 
disappear.

Actually I am unable to reproduce the issue in my office (simple unmanaged 
network), so possibly there is something wrong with the local network on the 
customer site.

I guess I'll have to go back on customer site at some point, however, I would 
like to prepare a few "weapons" that would allow me to gather some further 
information about what's going on. Any idea what could be helpful to figure out 
what the problem is ? Is there any way to configure Live555 so that it output 
some logging information or something ? That's not an easy one, really :/

When you ‘close’ “ffplay”, is it sending a RTSP “TEARDOWN” command to the 
server?  Or are you just killing it with <control-c?  If the latter, then the 
server has no way to know that the RTSP TCP connection is no longer being used. 
 It will wait for a period of time (by default, 65 seconds) to check whether it 
sees any more activity on that TCP connection.  Then, and only then, will the 
server close the TCP connection.

So, if your client - for whatever reason - is starting, then killing “ffplay” 
several times in a row, then the server will keep each of these TCP connections 
will stay open for 65 seconds before reclaiming then.
