In order to delete the many Content Deployment Timer Job records that are created during the automated content deployment process follow the steps below:

1. Run the following SQL statement on your SharePoint Config Database to retrieve the unique IDs (GUIDs) of all the Content Deployment Timer Jobs:

    select * from Sharepoint_Config.dbo.[Objects] REM where [Name] like 'ContentDeploymentJobDefinition%'

2. Then, use those unique IDs (GUIDs) to build a batch file to run the following STSADM command:

   STSADM -o deleteconfigurationobject -id "<object id>"

Lately, we have been getting a lot of errors on our content deployment jobs.  The error that the jobs seem to have in common is “An update conflict has occurred, and you must re-try this action”.

I followed this Microsoft KB Article to resolve the issue: Error message when you try to modify or to delete an alternate access mapping in Windows SharePoint Services 3.0: "An update conflict has occurred, and you must re-try this action" – 939308
