  winbindd: Exceeding 200 client connections, no idle connection found

I'm getting above error on the winbind services which are causing several issues such as disconnecting users from active transfers and reprompting user credentials that doesn't accept user info.
I found this closed bug on version 3.0.2 smbd version that had this error but I'm not sure if I'm looking at the same problem on the version 4.x

Does anyone else have similar issue with the version 4.1.6?
