Discarding too old outgoing packet

Hi guys. We got some CPU spikes today, which cause service degradation. Janus logs have a lot of ‘Discarding too old outgoing packet’, any idea what can be reason for that? Attaching logs too. Thanks!

The cpu spikes likely cause the “discarding too old packets”.
The real question is what is causing those spikes.

Encountered the same issues.
Now, planning to decrease the bitrate.
But how to improve nice_agent_send performance?
