Describe the issue

The application panics and there is no way of avoiding it. This happens when mediamtx receives a stream and in the same moment you ask the get streams api.
I've only tried with RTMP but this could also be the case with also the other protocols (srt, hls, webrtc, rtsp)
I'm guessing it's some kind of concurrency issue.
Please help because this issue is really critical for my use case, I need to get the status of the connections quite often and I can't have this issue in production. Thanks

Describe how to replicate the issue

1. start the server
2. publish a stream with rtmp
3. call the http://localhost:9997/v2/rtmpconns/list API

Did you attach the server logs?

serverlogs.txt

yes

Did you attach a network dump?

no

When I remove the bytes received line I don't have the issue anymore. It's most likely some concurrency issue correlated to this (rtmp_conn.go line 648)
