Hello  
I deployed openvidu server on the ubuntu16.04.  
I installed it by following [https://openvidu.io/docs/deployment/deploying-ubuntu/](https://openvidu.io/docs/deployment/deploying-ubuntu/)  
It works, but the server crashes 1~2 times/day that is because KMS is crashing.  
I checked the logo file but it says: “Element rtpbin106 already has a pad named send\_rtp\_sink\_1, the behaviour of gst\_element\_get\_request\_pad() for existing pads is unde$”  
Here is screenshot.  
[https://prnt.sc/rndz3m](https://prnt.sc/rndz3m)  
Please let me know what is this issue and how can I prevent the KMS crashing.  
I need this done very quickly and I might get a lot of bad feedback from users if I don’t resolve this soon.

thanks

We discovered this is caused by multiple videos being requested by Safari browser. Multiple videos in the same WebRTC connection is not supported by KMS, but it wasn’t being correctly handled, so it failed.

A priority patch was pushed and released for KMS 6.13.1. Now it should work fine with Safari, so please upgrade your KMS version following the instructions shown here: [Kurento local upgrade](https://doc-kurento.readthedocs.io/en/latest/user/installation.html#local-upgrade).
