I was checking if the modification you posted me were compiled in.
My latest pulled source of that file (smb_lgrp.c) at line 1106 is:
---------
for (i = 0; i
char *tname;
if ((wka = smb_wka_lookup_name(builtin[i])) == NULL)
continue;
if ((tname = strdup(wka-wka_name)) == NULL)
return (SMB_LGRP_NO_MEMORY);
if (!smb_lgrp_exists(tname)) {
rc = smb_lgrp_add(tname, wka-wka_desc);
if (rc != SMB_LGRP_SUCCESS) {
syslog(LOG_DEBUG, "failed to add %s",
tname);
}
}
free(tname);
}
return (SMB_LGRP_SUCCESS);
-------------
looks like the modified one you posted.
Here are the compiling log rows about that file:

Hi, so many thanks for posting me this, looks like the problem is really the same.
Actually it's my own distro composed of illumos kernel + needed libs from openindiana required by
distro_const.
I looked at the patch, and it looks to be present inside my current illumos-gate repository, last
checked out on may and used to build everything.
Both smbd and libsmb.so inside the illumos-gate build are same size as the one on the running
machine experiencing the problem.
As far as I know, these are parts of the illumos kernel not depending on the additional OI libraries
required to make a running system, so I suspect this may not be the result of the merging by distro_const.
As long as the patch is there in my sources, would you suggest a pull of the sources and rebuild
anyway?
Or is there any other place I should look to check?
Could you please provide mdb's ::stack output?

Oggetto: [OpenIndiana-discuss] smbd core dumps and transitions to maintenance
Hi,
looks like kdb5kdc was not the cause of problems (looks like...).
I created the principal through the kerberos tool, restarted the machine and it was all fine.
So I joined again my domani via smbadm, and after some trying to connect to the shares (falining),
I found again smb was down in maintenance.
I found many core.smbd.xxxxxxx files, but I can't find a reason for it....and I can't find smbd.log anywhere.
I tried starting smbd manually, but it fails requesting the smb.conf, that I never had....
here's the pstack of one core:
# pstack core.smbd.1346233592
core 'core.smbd.1346233592' of 24103: /usr/lib/smbsrv/smbd start

I wonder what OI version you are using, we had a problem with libsmb
compiled using gcc (https://www.illumos.org/issues/1863), but it was
fixed long ago. Additional details would help here.
