smbstatus -b show too many samba connections ,when I update the windows defender in windows 10 pro

Dear all:

 I have a linux file share server  using samba 

samba package version is as below :

   samba.x86_64       4.4.4-9.el7

I use windows 10 pro PC to access files which is in file share server.

recently， i update the windows and virtus & threat protection .

but i get thousands of samba link by using the linux command "smbstatus -b"
at linux file share server, the user is nobody.

   nobody       nobody       x.x.x.x (ipv4:x.x.x.x:50142)      SMB3_11

when i disable the windows defender , it have no nobody samba link .

how can I deal this ?

thanks
