This article was previously published under Q237611



SYMPTOMS
Components of the SMS Executive service on a Systems Management Server 2.0 site may stop responding (hang) or experience performance degradation when the SMSExec_Prochist.dat file grows to a large size. This file is located in the SMS\Data\Prochist folder on a Systems Management Server 2.0 site server.



CAUSE
The SMS Executive service does not delete the SMSExec_Prohist.dat file when the service is started.



WORKAROUND
On the Systems Management Server site server exhibiting this problem:
 * 1) Stop the SMS Executive service.
 * 2) Delete the SMSExec_Prochist.dat file in the SMS\Data\Prochist folder.
 * 3) Start the SMS Executive service.



STATUS
Microsoft has confirmed this to be a problem in Systems Management Server version 2.0.



MORE INFORMATION
Because of the nature of this problem, it is not easily noticed. Consequences of this problem might include packages taking too long to get distributed in the site or to other sites, or client component upgrades at the site might not get propagated to Client Access Point servers in a timely manner.

The process history file (SMSExec_Prochist.dat) is used in conjunction with status messages reported by the components of the SMS Executive service. Before creating a status message, the component thread scans the file. If the file has grown to a size larger than 500 kilobytes (KB), there may be an adverse affect on the overall performance of the site server. In severe cases, certain components may appear to have completely stopped without producing any error messages.

This condition may affect the following components:
 * Client Install Data Manager
 * Inbox Manager
 * Inbox Manager Assistant
 * LAN Sender
 * NT Logon Server Manager
 * NT Logon Installation Manager
 * Winnt Server Discovery Agent
 * Scheduler

This problem does not apply to SMS components that are not part of the SMS Executive service.
