Are you sure that the workflow step is not triggering a new workflow?
Do you tigger the workflow on documents that are already stored by setting the Status to New manually or with Autoindex?
If you only want to trigger the workflow when the documents are stored, then uncheck the changed index entries.
Check each Task carefully to ensure that the status is changed to something other than New after the workflow starts, and ensure that it is never set back to New during the workflow.
This may not be the problem, but we should eliminate it as a possibility.
