Error: 1801 - Audit API export mailbox - deleted user and added alias to another user

[ashley]

Issued a request to export user mailbox

Request ID: 79960911

User: <user>@<domain>

Status: PENDING

Request Date: 2012-08-15 05:07

Requested By: <user>@<domain>

Requested Parts: FULL_MESSAGE

Request Filter: in:sent

Include Deleted: false

After 24 hours still shows up pending. Deleted the user from the domain and added the alias to another user name

Now if query the request I made I get an error 

Error: 1801 - Invalid value 79960911

Is there a way to delete this request or will get removed sometime in the future by google queue system

Google developers do you have any answer for this ????
