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

[Cameron Barfield]

Hi --

I cross posted this on the Blackfin forums, but I'm not entirely sure that this is a 
Blackfin problem.

I'm running Linphone 3.1.2 on a BF536. Alsa v1.0.18, oSIP2 v3.2.0, eXosip 
v3.2.0.

Everything works perfectly for 1,007 calls. Terminating the 1,007th call causes 
some problems:

That all goes on for a while, then:

ortp-error-Could not find default routable ip address !
linphone_core_get_local_ip() could not find default routable ip address


I added some printfs() to help track the problem. I added some code that would cause 
Linphone to terminate if linphone_core_get_local_ip() failed. Before that, Linphone would 
continue making calls successfully, but with no audio and all of the error messages above.

After terminating Linphone, sound no longer works at all. I used amixer to reset the mono 
playback switch, master volume, PCM playback volume, etc. but sound does not work until I 
reboot my board.

I'd originally suspected the path of the problem to be:


linphonec_main_loop()
linphone_core_invite()
linphone_call_new_outgoing()
linphone_core_get_local_ip()
exosip_guess_local_ip()
exosip_guess_ip_for_via()
exosip_default_gateway_ipv4()
setsockopt()

It looks like that path is hitting and failing, but it's not the start of the problem. I 
find it quite odd that it always fails when terminating the 1,007th call and that Alsa and 
the socket both go to lunch at the same time.

I'm going to try to get the same setup running on an x86 PC to see what the 
results are.
