Technical Solution



The Deployment Server engine (axengine) is so busy processing logged-on user data from its clients that it experiences severe performance degradation which includes, but is not limited to, jobs failing to run.


DS 6.9 (all builds)

Citrix and Microsoft Terminal servers with AClient or DAgent installed


The AClient/DAgent gathers each logged-on user's information and passes that information back to the Deployment Server engine (axengine).  The engine then has to process each of these bits of information. Because of their roles, both Citrix and Microsoft Terminal Servers generate high volumes of logged-on user data that trigger the failure described by this article.


This issue has been resolved by adding a registry key to the client that opts to ignore changes to the list of logged on users. This registry key will work on AClient 6.9.453 (SP4) or DAgent version 6.9.490 (SP5) and newer.

The key is:

HKLM\SOFTWARE\Altiris\Client Service\UserInfoInterval

Set the value to 0 to disable updating the list of logged-on users.
