We use the original vendor patch files during the deployment process. The patches are executed in unattended mode during the deployment. If there is an error during the installation of the patch, or user intervention is required, this may cause the patch to 'hang'.
It sounds as if you have identified the 'problem' patch. Try executing the patch manually in order to determine the cause of the failure. If you are still unable to identify the issue, telephone support is available from 07:00 until 19:00 CST, Monday through Friday at 800.690.6911.
