A/V Edge - 01 - TCP Counters\- 006 - Allocate Requests Exceeding Port Limit/Sec\_Total

A_V_Edge___01___TCP_Counters___006___Allocate_Requests_Exceeding_Port_Limit_Sec__Total_20__MR (UnitMonitor)

A/V Edge - 01 - TCP Counters\- 006 - Allocate Requests Exceeding Port Limit/Sec\_Total perf counter exceeded specified threshold. Current value is {0}

Knowledge Base article:

Summary

The per-second rate of allocate requests over TCP that exceeded the port limit.

Causes

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.

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 originator of messages requesting more than the permitted number of ports to allow further troubleshooting of the cause.
