Multiple RRAS Client Disconnects Cause Increased CPU Usage

CAUSE

During a client's connection, the router will allocate memory on the server to perform a query against the interface table, allocating memory for the whole table. It does so by looking at the count of interfaces and allocates an amount equal to the number of connections multiplied by the number of bytes used by the router's interface table. Clients who dial in are counted as an interface by the router and are added to the table. However, when a client disconnects, the system does not decrement the connection count and subsequent connections continue to add to the size of the table. Repeated queries on the increasingly large amount of memory allocated to the router interface table results in the perceptible slowdown of the server.
