Sequential Tasks are executing multiple times or are stopping part way through the sequence and not completing. These two symptoms have been caused by the same defect.
This was caused by a handling defect within the Task Synchronization Agent.
A hotfix has been developed and tested to resolve this issue. The hotfix is attached to this knowledgebase article (link found in the left-hand pane). The hotfix upgrades the Task Synchronization Agent and updates the collection assigned to the Task Synchronization Agent Upgrade Task to incorporate the version change.
Note! If you've previously installed a version of this hot fix prior to 2009-02-18 you will need to uninstall the previous version of the hot fix from Add/Remove Programs before reapplying with this newer version. The latest release is version 6.1.1032.
To apply the hotfix, simply run the attached EXE on the Notification Server (located in the right-hand pane). Note that processing will be paused during the application of the hotfix. It is recommended to either log directly on the Notification Server or use the /console switch if using Remote Desktop.
To finish the fix, use the Task Synchronization Agent Upgrade policy to roll out the new version of the Task Synchronization Agent.
In the Altiris Console, browse to View > Solutions > Software Delivery > browse through Configuration > Task Synchronization Agent.
Right-click on the Task Synchronization Agent Upgrade task and choose Enable (if not so already).
If an upgrade has occurred previously, please set a schedule to roll out the new Agent as the option for Run as Soon as the Computer is Notified only ever runs once, regardless of changes in version.
