The per-second rate of allocate requests over TCP that exceeded the port limit.
This error occurs when there is an unexpectedly high rate of requests over TCP for ports associated with the same user ID. This could be an indication of an attempt to misuse the A/V Edge Server.
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 originator of messages requesting more than the permitted number of ports to allow further troubleshooting of the cause.
