Symptoms

On a Microsoft Windows 2000-based domain controller, memory usage may continue to increase, and you may have to periodically restart the server. If you use System Monitor to view the Local Security Authority Service process (Lsass.exe), you may see that memory usage for the Lsass.exe process continues to increase. The following Error event may also be logged in the event log:

Event Type: Error
Event Source: NTDS General
Event Category: None
Event ID: 1168
Description:
Error 8(8) has occurred (Internal ID 3020239). Please contact Microsoft Product Support Services for assistance.

Note To monitor the Lsass.exe process, see the Process\Private Bytes and the Process\Virtual Bytes performance counters in System Monitor.

Cause

This problem may occur when event tracing for Security Accounts Manager (SAM) events is enabled. When event tracing for SAM events is enabled, the remote procedure call (RPC) binding is not released. Therefore, a memory leak occurs in the Lsass.exe process.

Workaround

To work around this problem, disable event tracing for SAM events.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More information

To determine whether event tracing is turned on for SAM events, run the tracelog.exe -l command. This command lists all the trace sessions that are active. The output that this command produces does not identify the events where event tracing is enabled. However, you can use the information that is contained in the Logger Name field to determine the application that turned tracing on. You can also stop all tracing sessions by running the tracelog.exe -x command.

Note The Tracelog.exe utility is provided with the Windows 2000 Resource Kit. For more information about the Windows 2000 Resource Kit, visit the following Microsoft Web site:
