which smbd.log? I guess you're referring to the NetAPP event log 
fragment you shared? Nobody outside NetAPP will be able to do a failure 
analysis based on the NetAPP log.

Here on planet Samba we could ony look at at SMB network trace between 
client and netapp, network traces of all traffic of the netapp appliance 
(mainly to look at DNS, the RPC connection to the DC will be encrypted) 
and a log with level 10 from the Samba DC.

With a bit of luck it's possible to find something where thing go south, 
but it's a slim chance.
