sample length is overshooting max datagram size log file entry

Good Day All

I have the following entry persistently displayed in my DELL PCT6248 and 7048 buffer log:

sFlowReceiverFlowSampleAdd: sample length is overshooting max datagram size.

ALL my receivers are configured as follows:

Net_Mgmt_Test_1#show sflow 1 destination

Receiver Index................................. 1

Owner String................................... Net_Mgmt_1_Test_1_1/g48

Time out....................................... 4272364975

IP Address:.................................... 192.168.5.145

Address Type................................... 1

Port........................................... 6343

Datagram Version............................... 5

Maximum Datagram Size.......................... 256

Net_Mgmt_Test_1#show sflow 1 sampling

Sampler         Receiver    Packet                Max Header 

Data Source  Index          Sampling Rate   Size 

-----------         -------           -------------           ---------- 

1/g48                1                 1024               256

Net_Mgmt_Test_1#show sflow 1 polling

Poller              Receiver    Poller 

Data Source   Index         Interval 

-----------          -------         ------- 

1/g48                1              256

I use Solarwinds NPM and NTA for my traffic analysis.

Can anyone explain why this is happening and possibly offer me some guidance on configuring the Sflow parameters optimally?
