How do I track down QOS "Aggregate Drops" in a 6807-VSS switch?

IOS = 15.1(2)SY1

 

When I do a "show platform qos" everything looks good except for this:

 

 ----- Switch [1], Module [3] -----
                 Counter                  IFE Pkts        IFE Bytes                 OFE Pkts           OFE Bytes
----------------------------------------------------------------------------------------------------------------------------
          Policing Drops        0                         0                                216304              16888896     
       Policing Forwards     2935238201     5068976519092     2949830653     5069751062945
Police-hi Actions (Lvl3)    0                         0                                0                          0            
Police-lo Actions (Lvl2)    0                         0                                0                          0            
         Aggregate Drops    0                         0                                263889               16888896     
      Aggregate Forwards 2935238198     5068976518864     2949830650      5069751062717

 

Any idea if these drops are QOS related and/or how to get more information about them in order to troubleshoot?  OFE means 'Output Forwarding Engine'.   There are no input or output queue drops on any of the interfaces doing a "show interface gx/x/x."

 

Thanks.

Aggregate drops is just a

Aggregate drops is just a total of drops from all the different internal processes.  The OFE Bytes matches the policing drops.  I'd assume policing is what caused these drops.  The packet number difference may be due to fragmentation.
