Hi, I have a Samba AD domain running 2 self compiled 4.7.3 DC's running on Centos 7. Every morning if I run wbinfo -u on DC1 I do not get any info back. I have tried reloading samba but that does not get it working. Restarting samba seems to be the only way to get it working again. DC2 continues to work normally. DC1 holds the FSMO roles and also runs bind DLZ and ISC dhcp configured per the samba wiki articles. DC2 is only acting as a DC and DNS server with bind_DLZ. The smb.conf files are the same on both DC's. The smb.conf is as follows: [global] realm = KMG.MYDOMAIN.COM server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate workgroup = KMG server role = active directory domain controller idmap_ldb:use rfc2307 = yes log file = /var/log/samba/%m.log max log size = 5000 log level = 2 idmap config KMG:unix_nss_info = yes template shell = /bin/bash template homedir = /home/samba/users/%U deadtime = 5 [netlogon] path = /usr/local/samba/var/locks/sysvol/kmg.mydomain.com/scripts read only = No [sysvol] path = /usr/local/samba/var/locks/sysvol read only = No When things are not working a ps shows the following: (vdc1 pts6) # ps axf | egrep "samba|smbd|winbindd" 111627 pts/6 D+ 0:00 | \_ grep -E --color=auto samba|smbd|winbindd 36675 ?

I do not see anything obvious in the logs. Does anyone have any idea how to troubleshoot this? Is there something in particular I should be looking for in the logs? Regards, -- Tom me at tdiehl.org
