Bad Request

When I try to sync I keep getting "Bad Request"
Here's the information from the log file that indicates a Duplicate entry
How do I determine what the entry is for '125669-993-0'

[2011-07-17 19:21:54] >>> Callback ({status:400, message:"(1062, \"Duplicate entry '125669-993-0' for key 'PRIMARY'\")"})
[2011-07-17 19:21:54] Returned error: Bad request(400)
