A_V_Edge_02_Total_Counters_027_Active_Sessions_Exceeding_Avg_Bandwidth_Limit__Total_20_2_MR (UnitMonitor)

A/V Edge - 02 - Total Counters\- 027 - Active Sessions Exceeding Avg Bandwidth Limit\_Total perf counter exceeded specified threshold. Current value is {0}

Knowledge Base article:

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.
