the wireshark capture fire filtered with "udp.port == 60841" which will show the whole process of the error.

[Eric Rescorla (:ekr)]

The encrypted alert is generally a sign that Firefox is trying to close the connection.

Please rerun with the logging settings described here for signaling and transport
and post the results.

yes, we used to get the log,
but the log file will be re-written soon after about 5seconds.
how to make the log file not be re-written.

thanks

That's the WebRTC.org log. The log files I indicate above are not rewritten.

i rerun once more with log level = 1 and find above error :"GetAVStats failed" and then after about 30seconds, the connection closed.
more log is attached in copy(2).7z

by the way, we just use audio and do not enable video

hi,eric, 
i have posted the log 

thanks

Well this seems fairly clear:

2015-03-03 06:04:03.401000 UTC - 0[5711140]: [main|PeerConnectionImpl] PeerConnectionImpl.cpp:1835: 2015-03-03 06:04:03.401000 UTC - 0[5711140]: [main|PeerConnectionImpl] PeerConnectionImpl.cpp:1835: sipcc::PeerConnectionImpl::CloseInt: Closing PeerConnectionImpl f3a7061f559206f3; ending call


Here's the relevant line of code:
https://hg.mozilla.org/releases/mozilla-release/file/7e01afd0e736/media/webrtc/signaling/src/peerconnection/PeerConnectionImpl.cpp#l1834

It looks to me like the only places that CloseInt are called from are:

- PeerConnectionImpl::~PeerConnectionImpl()
- PeerConnectionImpl::Close()

PeerConnectionImpl::~PeerConnectionImpl() logs at the level info prior to
calling CloseInt(), so I suspect that someone is somehow calling
PeerConnectionImpl::Close();

Are you perhaps allowing the PC to get garbage collected in the JS
or calling .close() on it?

Comment 16

[39378154]

eric, thanks for your response soon,
a) our code will not call .close() at that time,the same code run in chrome will not disconnect.
b) and i am not sure whether it is the encrypted alert make the disconnection or the disconnection make the encrypted alert.

c) by the way, we do not " allowing the PC to get garbage collected in the JS", and same code run in chrome is ok.

I'm pretty sure that CloseInt() is causing the alert, since
the major thing that causes alerts in this case is shutdowns.

Well, just because there's no problem in Chrome does not mean that
the problem is in Firefox.

I would advise you to build your own copy in Firefox and put a breakpoint
in CloseInt() so we can see what's making it happen.

If you want to post uncompressed versions of the logfiles, I'll take a look
(I don't have the appropriate unzipper on hand) but I expect it will not
tell us any more than I said above.

Comment 18

[39378154]

ok, let me try to put a breakpoint.

Comment 19

[39378154]

CloseInt() is c++ code, how to set breakpoint for it.

Comment 20

[39378154]

thanks eric,
we found the root cause, and fix it. it is our code issue. 
the peerconnection status in firefox is not same with chrome .

by the way, i test firefox with tcp candidate but firefox can not connect in.
my question is : does firefox support tcp.

thanks

Firefox supports TURN-TCP but does not presently support ICE-TCP

ICE TCP is Bug 891551
