[Samba] Problem to many connection

[Epsilon Minus]

I'm desperate. My English is terrible, but I will try to be as clear as
possible.

I have Samba 4.4.4 in a Centos 7.

I have many connections for each ip.

The command smbstatus -b returns me infinity of these:

And repeat to infinity.

I've been with this for many hours and I can not find the problem. I'll be
very greatful.
