There isn’t much to go on.

Are there any messages before these in the logs?

Are origin and edge servers on the same Wowza version?

This can happen under situations where bandwidth is insufficient to Wowza,

as there is not enough data, or there is packet loss, so Wowza is expecting more data than is available.

Best regards,
