Ah, so that's where I can tell SMF to leave things alone. I concur. 
Running smbd unmanaged has resulted in zero samba downtime. As for the 
core dumps...

In the logs: smbd[22213] setid process, core not dumped:

coreadm
      global core file pattern: /var/cores/%d/%f.%p.%n
      global core file content: all
        init core file pattern: core
        init core file content: default
             global core dumps: enabled
        per-process core dumps: enabled
       global setid core dumps: enabled
  per-process setid core dumps: enabled
      global core dump logging: enabled

What am I missing?
