Client libraries NodeJS "kurento-client": "6.6.0"

System description:

All on local network

What steps will reproduce the problem?

We are using single connection to KMS which creates pipeline, creates WebRTC and Recording endpoint and connect one to another. Recording works but when we close and destroy old pipeline and create a new one then server often crashes (not always).

What is the expected result?

No crash.

What happens instead?

Crash. In media-server_error.log I see:

Segmentation fault (thread 139804290828032, pid 10713)
Stack trace:

and sometimes I see

Segmentation fault (thread 140684067280640, pid 11095)
Stack trace:

(kurento-media-server:11324): GStreamer-CRITICAL **: Element rtpbin3 already has a pad named recv_rtcp_sink_1, the behaviour of  gst_element_get_request_pad() for existing pads is undefined!

Does it happen with one of the tutorials?

No

Now it crashes when calling method create with {"type":"WebRtcEndpoint","constructorParams":{"mediaPipeline":"550bbc27-ecd2-4fe5-9248-1a9ea5c0293b_kurento.MediaPipeline"},"sessionId":"d2024828-bcba-43a8-9ebc-0c16bcd23fd4"} with just Segmentation fault without any details.

Another crash: invoke {"object":"6e3b4e59-6af3-4ba0-bd74-f896d6483321_kurento.MediaPipeline/a9adaedb-4e31-4c5b-9800-aecc439068cf_kurento.RecorderEndpoint","operation":"stop","operationParams":{},"sessionId":"559ec20d-c068-482c-b27c-5eb57ce8fe2b"}

zdila commented 7 years ago

OK, so the last two problems get fixed if I release old Recording and WebRTC endpoints. Still this is no reason for crashin or freezing kutenro.

jcaden commented 7 years ago

Have you done a standard installation? I mean are you using a clean ubuntu 14.04 box and using just kurento compiled packages?

zdila commented 7 years ago

Yes. Using vanilla 14.04 with all the security updates it offered.

zdila commented 7 years ago

I've also tried 6.6.2 (dev) version today with the same results.

jcaden commented 7 years ago

What kind of client are you using, as this seems to be doing something strange with ssl. Additionally check your locale, as we know that locales different that English could cause problems.

zdila commented 7 years ago

For websocket we are using https://github.com/websockets/ws and the connection is not secured (SSL). For WebRTC we are using Chrome 54 and Firefox 49, 50.

Environment variables taken from /proc/<pid>/environ are:

XDG_SESSION_ID=c38

INSTANCE=
XDG_RUNTIME_DIR=/run/user/1001
_=/usr/bin/kurento-media-server

The only modification is that we reworked start sript from init.d to upstart so that it respawns crashed Kurento. Still it can't handle frozen Kurento. And it was crashing the same way with the default startup script.

We have 2 instances, both problematic. One runs in VirtualBox (image from OSBoxes) and another in Linode.

zdila commented 7 years ago

Anything else we could try? This issue is a pretty blocker for our solution.

zdila commented 7 years ago

Can we get any commercial support?

jcaden commented 7 years ago

Having a detailed description of the pipeline you are running, or even the logs will be very useful to fix the problem, as it is something that we can't reproduce.

zdila commented 7 years ago

I've managed to import projects (kms-core and kurento-media-server) to Eclipse Neon CDT and debug it there. Here is the screenshot of the crash (copying of the stack trace didn't work): image

I must still figure out tow to tell Eclipse to search for source not in /opt/kurento/kms-core but in the imported project. And also to use kms-core binaries produced by Eclipse. Coming from Java and Nodejs world it is not much straightforward for me yet.

I'll add here also the dump of the websocket communication soon.

zdila commented 7 years ago

Pipeline looks like this:

pipeline

After the pipeline is constructed it works correctly. Then media change comes so we are destroying old pipeline before creating a new one but it makes Kurento crash. But not always. Sometimes it survives.

Currently it crashes on calling RecorderEndpoint.stop().

The error

GStreamer-CRITICAL **: Element rtpbin1 already has a pad named recv_rtp_sink_1

that could be seen in Kurento logs was (most of the time) due to mistakenly adding more than 1 video and/or 1 audio media stream track to the RTCPeerConection object in the Javascript side of the application. This would try to negotiate multiple videos or audios, and cause critical warnings inside the GStreamer code in KMS.

Of course if KMS is not able to handle multiple media tracks, it should reject the medias in the SDP negotiation, not crash or cause internal GStreamer-CRITICAL warnings. That bug was solved with commit https://github.com/Kurento/kms-core/commit/6a47630cba2aba4c74527f9757b705c342da5106, available since Kurento 6.13.1.

Please reopen if any of the other reported crashes still happen.
