SYMPTOMS
On Windows Server 2003 R2-based computer, if you enable the Quota function of the File Server Resource Manager (FSRM) component, the Windows Server 2003 R2-based computer may stop responding. This problem occurs because of paged pool exhaustion. When this problem occurs, all programs and services stop working.

Additionally, an event that resembles the following event may be logged in the System log:

Event Type: Error

Event Source: Srv

Event Category: None

Event ID: 2020

Date:

Time:

User: N/A

Computer:

Description: The server was unable to allocate from the system paged pool because the pool was empty.



CAUSE
This problem occurs because the Quota.sys filter driver of the FSRM component does not correctly manage the allocated paged pool. Therefore, a memory leak issue occurs in the paged pool. When the paged pool is exhausted, this problem occurs.
