Monitor Knowledgebase

Summary

The number of active relay sessions over UDP that are exceeding bandwidth limit.

Causes

This error occurs when there is an unexpectedly high rate of traffic sent through the A/V Edge Server within a UDP session. These sessions will be throttled by the A/V Edge Server. This could be an indication of an attempt to misuse the A/V Edge Server.

Resolutions

Check that the profile of network traffic to the A/V Edge Server is in line with expected usage. A network level trace can be used to determine if there is unusual amount of traffic originating from a single source. If the situation persists then enable tracing to identify the participants in sessions exceeding the bandwidth limits to allow further troubleshooting of the cause.
