We use the kamailio with dmq. One Kamailio gets an SIP Register and process it and
forwards it though DMQ to another kamailio. here it should be saved in location as well.
During saving this location the kamailio crashes. For me (not an dev) it seems to crash
during getting the length of the AOR. This is not happening every time while kamailio gets
an DMQ register but we can reproduce it very easy. (at least this is the line pointing to
referred in the backtrace)
the SIP DMQ Message looks like
Oct 20 14:44:53 messi /usr/sbin/kamailio[15059]: NOTICE: <script>: Got KDMQ

Can you show the definition of table location? Is the username column a varchar and has
not-NULL constraint?
Also, check to see if there is a record with ruid=uloc-562103eb-6411-a4a1 and if yes, what
is the value for username column?

Hi Daniel,
the location looks like:
CREATE TABLE `location` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`ruid` varchar(64) NOT NULL DEFAULT '',
`username` varchar(64) NOT NULL DEFAULT '',
`domain` varchar(64) DEFAULT NULL,

`q` float(10,2) NOT NULL DEFAULT '1.00',
`callid` varchar(255) NOT NULL DEFAULT 'Default-Call-ID',
`cseq` int(11) NOT NULL DEFAULT '1',
`last_modified` datetime NOT NULL DEFAULT '1900-01-01 00:00:01',

PRIMARY KEY (`id`),

and yes there is an entry for this ruid with username "1016811e7"

Can you get the output in gdb, frame 0, for:
```
p (ROW_VALUES(RES_ROWS(res)))[19]
```

Hi Daniel,
we are not sure how to get this value. I tryed to select frame 0 and just paste the line
you provided.
this is what happend:
(gdb) select-frame 0
(gdb) p (ROW_VALUES(RES_ROWS(res)))[19]
No symbol "ROW_VALUES" in current context.
(gdb)
i guess this is not what you need. Can you give us more specific instructions? Would it
help we provide the backtrace it self? it's about 80Mbyte

So that value seems invalid.
Looking at the code I see that this is done during a delete contact operation. Is your
usrloc configured with db only mode? Because is doing query to database, not using the
cache.

yes it is. The purpose of that kamailio is not having sip call traffic but only save the
location in DB.

Looking at the sources I think there was a mistake interpreting a return code in
dmq_usrloc -- can you try with patch 13cde2bb1deda9cc67925ca01910e41150c4435e (it is only
in master)?

After adapting the patch (a git cherry-pick would not work) it still crashes. I hope I did
it right, here is the new backtrace:

Thanks. Running now in our dev environment, no crash so far.
I would attach a patch that works against the 4.3 branch, but Github won't allow me to
attach .patch files (and no .txt neither, because I don't have write access to the
repository).
So this is the plain text patch, that works for us:

I will backport the missing patches to 4.3.
Github doesn't allow attaching patches/files, as I understood -- they recommend making
pull request instead of attaching patches (fork the repo, then push a patch to the clone
and initiate a pull request from the clone:
https://help.github.com/articles/creating-a-pull-request/ ).
