SYMPTOMS
Consider the following scenario. On a server that is running Microsoft Exchange Server 2003, you set the value of the RestrictionMethod registry entry to 2 to configure flat group restrictions on a connector. Then, you send many e-mail messages through the connector. The Exchange 2003 server runs for several days. When you view the Epoxy Bytes Allocated\DSAccess performance counter, you notice that the number of items increases. However, the number of items never decreases. The server finally becomes unresponsive and must be restarted. Additionally, the following event is logged: Event ID: 9582

Event Type: Error

Event Source: MSExchangeIS
