If nothing is connecting, then winbind shouldn't be doing much, so if
it is, you need to find out why.

Try running 'samba-tool dbcheck' on the DCs
Check replication between the DCs
Check the Samba logs on the DCs, is there anything relevant showing at
the time that winbind is overloading on the domain member
Raise the log levels on the DCs and domain members and see if anything
pops out.

One thing I noticed when I looked it your smb.conf again was this:


I take it this was just a typo when you sanitised it.

If this is only happening on one domain member, try comparing the
various files on one with the other (/etc/hosts, /etc/krb5.conf and so
