> Hi,
>
> Are you using --domain-critical-only switch when joining your new DC? This
> switch force Samba to copy only critical stuff when joining the new DC then
> this new DC will get all others objects using standard replication process.
> This switch helps a lot when Samba database starts to grow a bit. Without
> that switch the database is fully replicated during the join command in
> some process which looks like a big DB transaction (eating lot of memory,
> lot of time, adding possible issues)
>
> Hoping this solves your issue, kindly regards,
