Symptoms

When enabling Samba service in a Solaris 11.1 non-global zone the samba SMF service would enter maintenance mode and the smbd process being initiated would core dump.

The Samba log file log.smbd contained entries such as:

[2013/08/16 14:47:59,  0] smbd/server.c:1026(main)
 smbd version 3.6.12 started.
