My samba version is 4.1.3 and self compiled. My AD is running with win2003
I'm now use a server with 4G ram to join as DC. It's seams can run with use
4G more swap. But I have other problem. I run twice, after about 6 hour,
samba-tool domain join stop. Folow is some info:

samba-tool domain join mydomain.local DC
-Uadministrator at MYDOMAIN.LOCAL--server=win2003dc.mydomain.local

6h it stoped. Err message:
Partition[DC=gdsyzx,DC=edu,DC=cn] objects[222918] linked_values[0]
Done with always replicated NC (base, config, schema)
Replicating DC=DomainDnsZones,DC=gdsyzx,DC=edu,DC=cn
