samba - Aug 2016 - smbd signal 10 on start-up - Samba 4.4.5, Solaris 10

Greetings,

Have built and have Samba 4.4.5 running on my test Solaris 10 server.  
Works just fine on there.  It is set in /etc/system with ngroups_max=32 
and is running as a member server in my university's AD domain.

This morning trying to install 4.4.5 on a production server that had 
been running samba 3.6 - not "upgrade" but left the domain, installed 
the newer version of samba in an empty directory and then rejoined the 
domain.  When starting-up samba smbd dies upon start-up.

  I tried running smbd -i and see the following:

smbd -i
...
reghook_cache_add: Adding ops ff0c6b30 for key 
[\HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib]
pathtree_add: Enter
pathtree_add: Successfully added node [HKLM\SOFTWARE\Microsoft\Windows 
NT\CurrentVersion\Perflib] to tree
pathtree_add: Exit
regdb_close: decrementing refcount (1->0)
Finding user nobody
Trying _Get_Pwnam(), username as lowercase is nobody
Get_Pwnam_internals did find user [nobody]!
Finding user ROSE\nobody
Trying _Get_Pwnam(), username as lowercase is rose\nobody
==============================================================INTERNAL ERROR:
Signal 10 in pid 6077 (4.4.5)
Please read the Trouble-Shooting section of the Samba HOWTO
==============================================================PANIC (pid 6077):
internal error
unable to produce a stack trace on this platform
dumping core in /usr/local/samba/var/cores/smbd
Abort (core dumped)



Any ideas where I should start digging?   Troubling that test machine 
works fine while same software dies on the production machine.


Not having smbd die when connecting to a share which I saw a fair amount 
of before increasing ngroups

Add a 'panic action = /bin/sleep 999999' to the [global] section
of your smb.conf and then catch the parent process of the sleep
under the debugger to get a backtrace.
