Hi Anurag,
On reboot this morning, I found that I was getting some errors when running the
netcfg service along the lines of:
"cannot interpret user property"
This seemed to be down to missing netadm and netcfg users in my /etc/passwd.
So I added those from an older build, then I got a similar error on groups, and
so I added them.
What was different between this and older BFUs was that this was based on a
LU-ed snv_109 from snv_107, which never had these users. I did run acr, which
didn't report any errors to me - I would have expected this to merge the passwd,
shadow and group files but it didn't....
This is making me wonder if there is some other auths or similar missing, which
weren't merged with BFU, that is causing the sysevent errors... (more below).

I disabled netcfg, nwam and network/location, cleaned up the nwam configuration,
and set upgraded to false and then re-enabled these services. This seems to be a
cleaner configuration than what I already had (which should have also been an
upgraded configuration though... but seemed to be missing some NoNet and
Automatic locations, etc., but they are there now)
After this, I saw some more messages in the debug log that seemed to suggest
that it was working more as expected, but then I saw the same errors that Anurag
noticed w.r.t. nwamd restarting, in this light I picked up several core files,
they are all slightly different (attached is a series of pstacks) one common
point appears to be with umem:
feef5e05 _lwp_kill (2, 6, febfee3c, fee9a5de) + 15
fee9a5ea raise (6, fef90698, fee64110, fecd77b8) + 22
fecd77da umem_do_abort (fedb0200) + 2e
fecd79c3 umem_err_recoverable (fece6670, fecfdc68, 80a7908, fece6698) + 4f
fecd9a44 process_free (80a7908, 1, 0, 80b0a94) + e4
fecd9a7a free (80a7908, 2, febfef0c, fe8b48a8) + 1a
fe8b48ba nv_free_sys (fe8c92c0, 80a7908, 30, fe8b4fae) + 1e
fe8b4a69 nv_mem_free (8089908, 80a7908, 30, 80a7910) + 1d
fe8b4c8a nvp_buf_free (80898e8, 80a7910, febfef6c, fe8b503e) + 22
fe8b5077 nvlist_free (80898e8, 8074a08, febfef9c, fe9e2b70) + 47
fe9e2b87 nwam_free_object_list (80898e8, 80b0a94, febfefbc, fe9dd316) + 23
fe9dd337 nwam_loc_free (80ab188, 80b0b48, febfefcc, 805a3c8) + 2b
0805a44b nwamd_event_handler (0, fef85000, febfefec, feef088e) + 8f
feef08c6 _thrp_setup (fedb0200) + 7e
feef0b50 _lwp_start (fedb0200, 0, 0, feef088e, 0, 0)
and there are others without reference to umem.
I also noticed the message in my logs of:
nwamd[102635]: [ID 481907 daemon.info] 4: sysevent_bind_handle: Permission
denied
so it looks like the sysevent stuff isn't working correctly here.
I also have messages about importing my known wlans, like:
dub04wlan: could not add to known WLAN: unknown error
repeating for each known wlan entry from the 0.5 config file:
dub04wlan 0:13:c3:58:84:f0
sunwifi 0:18:b0:81:eb:c0
INSECURE 0:13:19:15:2f:80
E2-194 0:1a:70:62:8a:e0
attwifi 0:19:a9:79:ff:40
Parc 55 0:f:cc:24:ce:40
dub04wlan 0:13:c3:58:80:40
dub04wlan 0:13:c3:45:70:80
dub04wlan 0:13:c3:58:83:f0
dub04wlan 0:13:c3:45:6c:c0
dub04wlan 0:13:c3:58:98:d0
dub04wlan 0:13:c3:58:99:60
dub04wlan 0:13:c3:58:98:50
DarrenLucanWLAN 0:15:e9:27:4:1e
In the end, I'm still not getting any running network - I have to set up things
manually still.
Attached is the nwamd debug log for todays session...
Thanks,
Darren.
