SMB hammering the CPU - v6.3.5

[asktoomuch]

Hi guys,

 

I'm having an issue with my UnRAID after I upgraded to v6.3.5

I hadn't noticed this problem before, so I guess it appeared in the latest release.

 

When SMB is enabled (Settings => Network setting => SMB) and the default options chosen (Enable Yes (Workgroup), Hide No, Wokgroup WORKGROUP, Local master Yes), the CPU loads goes up to 100% in the dashboard and I see the "smbd" process hogging 50% of the CPU in command line (top).

 

And that's without any access to the drives, without the array being down.

 

Do you have any idea what could be causing that? I have had to disable SMB for the time being but that means I can't access my files anymore from Windows.

I have attached the diagnotics extract for your reference.

Thanks in advance for your help and let me know if you need more information.
