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.
