Thank you very much.However, update to samba-4.19.3 doesn't handle the issue.
The winbind coredump with Segmentation Fault the same as smbd in samba-4.12.15.First time it coredumped after 5 h running with "idmap config DOMAIN backend=tdb".Then I changed to "idmap config DOMAIN backend=ad","idmap config DOMAIN schema mode = rfc2307" and restart smb,winbind.It crashed again after 2 h running.I only have 5 domain user and gencache.tdb map_size is 61440 Byte.
The coredump file 1 as below:

Why it's always gencache.tdb unlock when coredump? If it is not a problem with samba, what else should I check?Any help will be appriciated
Best wish!

First, Samba shouldn't crash like that, but Samba 4.15.8 is EOL from
the Samba point of view, so can you try with a much later, Samba
supported version, your problem may already have been fixed.
Can I also suggest you fix your smb.conf .
All your users are being added to the Default '*' domain, rather than
the 'NS' domain (this is because there are no 'idmap config' lines for
the 'NS' domain).
The tdb2 idmap backend is really meant for a ctdb clustered
environment.
Finally, do you still really need SMBv1 ?
