Re: [Linphone-developers] Problem with Linphone 3.1.2 on Blackfin BF536

[Cameron Barfield]

Thanks for the tip. Running lsof shows over 1,000 open UDP sockets belonging to 
linphone.

I ran a Wireshark trace and the port numbers listed by lsof correspond with the RTP ports 
in the trace.

I added some more debug printouts and rtp_session_destroy() is being called and the calls 
to close() for the sockets is succeeding.

Why wouldn't the sockets actually close, though?
