As when troubleshooting anything like this, FULL logs for an event 
exhibiting the problem is in order.

So, a full transaction log of a delivery that resulted in duplicates. 
Not just the LMTP logs, ALL logs (including the postfix logs).

Since you are using NFS, and there are well known potential issues when 
using NFS under certain circumstances, a more detailed description of 
your (NFS) setup is in order.

Ie - are you using Director?
