AVMCU___00___Operations_AVMCU___000___Number_of_Conferences__4000_2_AVMCU (UnitMonitor)

AVMCU - 00 - Operations\AVMCU - 000 - Number of Conferences\ perf counter exceeded specified threshold. Current value is {0}

Knowledge Base article:

Summary

The number of active conferences on the A/V Conferencing Server.

Causes

The number of active conferences has far exceeded the expected usage and new conferences cannot be created.

Resolutions

If this high number of active conferences persists then the service should be restarted and logging enabled to identify if the rate of conference creation is in line with expected usage.
