This is likely a result of SMF detecting that something in the service
is sick (dumped core) and as such is performing a restart.  The
default configuration of the apache22 service is smart enough to
delegate this work to httpd, which already knows how to deal with
children that core dump.  From
/lib/svc/manifest/network/http-apache22.xml:

                <property_group name='startd' type='framework'>
                        <!-- sub-process core dumps shouldn't restart
                                session -->
                        <propval name='ignore_error' type='astring'
                                value='core,signal' />
                </property_group>


Perhaps the samba smf service requires a similar configuration.
