Unable to find encoding matching packet! packet

I just upgraded to latest jitsi-meet, JVB and prosody and now I lost audio within the meeting using electron, with the below Warning in the JVB logs :

Any idea the reason behind that ?

Best Regards,

I also observed the same error.

Any idea the reason behind that ?

Which JVB version you’re using @ninja ?
can you share the JVB logs ?

Full jvb logs will help, also if you know the specific call scenario when it occurred, that would be helpful (i.e. a conference with X participants, was there screenshare, etc.)

Sadly I can just add a “same issue here” without many details.

On an up to date jvb (2.1-376-g9f12bfe2-1 from .deb package), 8vCPU, 8Go RAM. Ubuntu Server. Average load 2.6.

Currently handling only 1 conference, 27 participants. 14 sending video, 3 sending audio. And in jvb.log I see about 50 messages per seconds “Unable to find encoding matching packet!”.

If I understand well, all these logs are related to only one participant. And jvb logs each packet received from this participant, as something is going wrong. Violent ! :slight_smile:
