Duplicated accounting records

[Marinko Tarlac]

Hi

I searched throw Internet and all I found was similar questions without 
detailed answer. :(

FR1.1.7 and MT as a NAS. I constantly receive these error logs. I'm 
using Mysql as a database and AcctUniqueId has unique attribute so as I 
can see during debugging process, mysql rejects duplicated AcctUniqueId. 
Is there any chance to figure out why NAS send this trash?
