SYMPTOMS
Consider the following scenario:
 * In Microsoft Exchange Server 2003, you enable the Message Tracking log.
 * In Exchange System Manager, you enable the RPC Calls category.

Note To enable the RPC Calls category, click MSExchangeSA under Services on the Diagnostics Logging tab. Then, click RPC Calls under Categories.

In this scenario, Exchange 2003 may perform slowly or may stop responding. Additionally, the following event is logged in the system event log: Event Type: Error Event Source: Srv Event ID: 2020 Description: The server was unable to allocate from the system paged pool because the pool was empty.



CAUSE
This problem occurs because a token handle leak exhausts the paged pool memory on the Exchange server. When the limit for paged pool memory is approached, the computer may start to generate event ID 2020 error messages.
