[Samba] Samba 4.1.9 - Could not find child error

[Krishna Harathi]

We are seeing this error in the logs every minute -

[2014/07/23 16:40:59.829260,  2, pid=13355]
../source3/smbd/server.c:437(remove_child_pid)

  Could not find child 19021 -- ignoring

I know there is an old bug/fix -
https://bugzilla.samba.org/show_bug.cgi?id=8269

smb.conf entries related to printer and printcap (disabled) -

load printers = no

printcap name = /dev/null

printcap cache time = 0

log level = 2

We want the log level to be 2. I see that the code - in Samba 4.1.9

if (child == NULL) {

                /* not all forked child processes are added to the children
list */

                DEBUG(2, ("Could not find child %d -- ignoring\n",
(int)pid));

                return;

        }

Question - Given the log level we want, how can we prevent these errors in
the log? Did I miss some parameter disabling printer/printcap completely?
How do we stop forking these untracked processes?

Does Samba 4.1X continue to  use source3 code base (as seen in the log
entry)?

Any help in this is appreciated,
