[Samba] Standby secondary domain controller

[David]

Hello,

I configured a main DC and secondary domain controller
successfully. The only problem is that I want the secondary DC to
Stand By, so most of the time it is shutdown.

The problem is that when the secondary DC is shutdown on the primary
DC I receive continously the following error which is filling the
logs:

Feb  1 14:23:56 saturno samba[3217]: [2014/02/01 14:23:56.021591,  0]

Is there a method to allow the secondary DC to be shutdown without
getting continously the above error?

Thank you in advance.
