High CPU and Memory Utilization When You Add Objects to or Remove Objects From the Active Directory (315697)
The information in this article applies to:
- Microsoft Windows 2000 Server SP1

- Microsoft Windows 2000 Advanced Server SP1
- Microsoft Windows 2000 Advanced Server SP2
- Microsoft Windows 2000 Datacenter Server SP2
This article was previously published under Q315697 SYMPTOMSWhen your server re-creates or imports objects into the
Active Directory, you may experience the following symptoms:
- The CPU utilization is higher than you expect during the
operation. If there are a lot of objects, the CPU utilization may remain at 100
percent for the duration of the operation.
- The Lsass.exe process may use more memory than you
expect.
- The Lsass.exe memory utilization may not decrease after the
operation is complete.
. CAUSEThis behavior occurs because the creation of Active
Directory objects is a pre-emptive operation. This means that the process takes
any available CPU cycles to allocate more threads for creation of new objects.
Additionally, Lsass.exe consumes any available RAM on the server, and retains
these resources after the operation is completed to be able to respond to
incoming queries as efficiently as possible. If memory is required for other
processes, the Lsass.exe caches decrease and memory is returned to the system.
STATUS This
behavior is by design.
