[Samba] Duplicate nobody pid entries from smbstatus

[Richard Tresidder]

Hi
   We've recently had a few windows 10 machines active on the network and are experiencing a strange issue in the output of smbstatus.
By the end of the day a windows 10 machine may be listed dozens of times in the PID listing, with the expected user once but then dozens of nobody:nobody entries also associated with the same machine / PID.
eg: a trimmed view..

Samba version 4.2.3
PID     Username      Group         Machine            Protocol Version
------------------------------------------------------------------------------
35585     nobody        nobody        192.168.0.41 (ipv4:192.168.0.41:51340) SMB3_00
35585     user1         user1         192.168.0.41 (ipv4:192.168.0.41:51340) SMB3_00
35585     nobody        nobody        192.168.0.41 (ipv4:192.168.0.41:51340) SMB3_00
35585     nobody        nobody        192.168.0.41 (ipv4:192.168.0.41:51340) SMB3_00

I've tried limiting the protocol tho SMB2_10, but the issue still occurs.
Has anyone else seen something similar? or be able to point me in the right direction?

Samba 4.2.3-11.el7_2
Centos 7
