I would like to make you aware that I have yum-updated Samba on several AIX servers to the latest code level available on AIX Toolbox and after each update noticed the same problem, which is that Samba -related errors occur on server shutdown and Samba does not automatically start on reboot.

I was able to identify the problem as being invalid links in subdirectories of the /etc/rc.d directory.

Here is what was showing after the code was updated:

Here is what the links need to be to work properly (I just backed up/restored the links from a working Samba server):
