SMS: Clients or Servers with SMS 2.0 Components Installed May Reach 100 Percent CPU Usage (281210)

SYMPTOMS

In some cases, the CPU usage on a Systems Management Server (SMS) client or server computer may reach 100 percent and may remain at 100 percent. This article describes one potential cause of this behavior.

Note that the behavior that is described in this article is not the only cause of 100-percent CPU usage on an SMS client or server computer.

CAUSE

This behavior can occur when the logging that is performed by the SMS client or server services in conjunction with the Cheyenne InocuLAN antivirus program cause the CPU usage to reach 100 percent. This behavior has been observed in, but is not limited to, the Smsapm32 client-side process and the Sms_Executive service.

WORKAROUND

To work around this behavior, use either of the following methods:

Stop the Cheyenne InocuLAN antivirus server service

-or-
Disable all logging for the SMS process or processes that are involved

NOTE: In some cases where hardware is either extremely busy or underpowered, you may have to spend a considerable amount of time to move through and stop the InocuLAN service.

RESOLUTION

To resolve this behavior, use InocuLAN driver version 5.0.4521.1 or later for Microsoft Windows 2000 or InocuLAN driver version 4.0.4521.1 for Microsoft Windows NT 4.0. This driver is located in the Ino_fltr.sys file.

MORE INFORMATION

The CPU usage can remain at 100 percent until you stop the InocuLAN service or restart the computer.

To check the version of your driver, click the Version tab in the properties of the Ino_fltr.sys file in the Winnt\System32\Drivers folder. Note that you must restart your computer to replace the existing driver files.
