Issue with smb2 file info request

Hello

I have issue with storage delay a request(see attached trace) that get file size info get more than 1.5sec

Looking on the trace i don't see any delay form storage side but i do see what seems to be authentication issues , and what more abnormal is that the full request should be \\10.2.0.21\dalet\LSU\Proxy\A103979.mp4 and chopped to smb.file \10.2.0.21\dalet ,my question what could be that the request is passed chopped a behaviour we see on others servers.

So i would like if someone could try to explain and help to understand what i see on that trace that is wrong

Please advice

Thanks
