Alert 4004

MCU <MCUname> is configured with insufficient user connections.

The system was unable to establish an additional management session connection to the specified MCU. Possible explanations:

●IP connectivity between the system and the MCU has been lost.

●This MCU doesn’t allow sufficient connections per user.

Polycom MCUs use synchronous communications. In order to efficiently manage multiple calls as quickly as possible, the Polycom RealPresence DMA system uses multiple connections per MCU. By default, a RealPresence Collaboration Server or RMX MCU allows up to 20 connections per user (the MAX_NUMBER_OF_MANAGEMENT_SESSIONS_PER_USER system flag). We recommend not reducing this setting. If you have a RealPresence DMA supercluster with three Conference Manager clusters and a busy conferencing environment, we recommend increasing this value to 30.

After a connection attempt fails and this alert is triggered, the system tries every 60 seconds to establish 5 connections to this MCU. If it succeeds, this alert is automatically cleared.
