[Error] 409 [Meaning/Causes] 
You have attempted to delete something that was still linked to something else in ARIN's database. For example, you tried to delete POC that is still linked to an ORG or NET, or you tried to delete a Customer that is still linked to a NET. This error may also occur if you attempt to add a nameserver to a Delegation, but that nameserver already exists for that Delegation, or if you attempt to remove the only nameserver from a Delegation with DS records. Additionally, you will see this error if you attempt to reallocate resources which are not within the parent NET you specify.
