            Bug ID: 203182
           Summary: WebRTC: MediaSoup Demo is crashing
           Product: WebKit
           Version: Safari 13
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Page Loading
          Assignee: webkit-unassigned at lists.webkit.org

When I load the official MediaSoup Demo in Safari, with a room of several people (around 15 people), the webpage is crashing in about 90% of the times. This happens after allowing to use the microphone, but before allowing to use the camera. The browser console doesn't show any errors.
In about 10% of the times, everything works perfectly.

These are the information I found so far:

- This only happens with Safari, if I use Chrome, it's always working.
- The crash doesn't happen if no other people are in the room.

Steps to reproduce:

1. Enter a room on https://v3demo.mediasoup.org/?roomId=k1vnakp4 with 15 people, e.g. by opening the same room link in 15 browser tabs in Chrome.
2. Now enter the same room with Safari on an arbitrary device.
3. Allow to use the microphone.
4. The webpage will be reloaded and the error "This webpage was reloaded because a problem occured." is shown.
5. Click on allow to use the microphone again.
6. The page is crashing completely and the error "A problem repeatedly occured with https://v3demo.mediasoup.org/?roomId=owhaa7lq" is shown.
