Hi Bogdan,
If I am able to get some useful debug info or a capture file then I will
send them directly to you.
The version of OpenSIPS that has the problem is 1.6.2-notls (x86_64/linux).
Here is output from successive opensipsctl queries after the Aastra phone
has been connected for about 15 hours:
[root at centos6v ~]# opensipsctl online
1003
[root at centos6v ~]# opensipsctl ul show

usrloc:registered_users = 16
usrloc:location-users = 16
usrloc:location-contacts = 1
usrloc:location-expires = 15
The stats are incrementing by one every hour – each time the Aastra sends
its registration request. Capturing the SIP messages shows there is a single
request (no auth challenge) and a single 200 Ok, as follows (this capture
was from more than 12 hours ago):

Hi John,
The stats are kept in memory (and calculate based on the data cached by
opensips) so, the DB should not affect at all the stats.
What is the opensips version where this happens ? if the issue is issue to
reproduce, could you get full debug logs for all registrations ?
Regards,
Bogdan

Hi Bogdan,
Here is another update:
The problem exists when I register an Aastra 6731i phone, but does not when
I register a Snom 360 phone.
As explained before, it does not happen at all on my Ubuntu test server. It
only happens on my CentOS test server. Both are running the same
opensips.cfg file, but they are running different versions of OpenSIPS. Both
are using a locally hosted MySQL database to store user data
(opensips.subscriber) and location data (opensips.location). I can see no
errors in the log files.
Do you have any ideas or suggestions for additional tests? For example,
should I reconfigure the CentOS OpenSIPS to use the Ubuntu MySQL server in
case it is a database problem?

Hi John,
I tried to reproduce this on live system and I do not see this difference:
tester001:~# opensipsctl fifo get_statistics usrloc:
usrloc:registered_users = 53
usrloc:location-users = 53
usrloc:location-contacts = 56
usrloc:location-expires = 84
tester001:~# opensipsctl ul show --brief | wc -l
54
Also running with DB mode 2.
The counter is decremented when a contact is removed from memory hash.

Bogdan

Hi John,
So you are saying that "opensipsctl ul show" shows only 2 records while the
statistic shows more ??

Bogdan,
Here is a snippet showing the significant parts from the script that I
use for handling REGISTER requests, but I think there is only one line
that is unusual.
modparam("usrloc", "nat_bflag", 6)
modparam("usrloc", "db_mode", 2)
modparam("usrloc", "use_domain", 1)
modparam("registrar", "default_q", 800) modparam("registrar",
"received_avp", "$avp(s:rcv)")
sl_send_reply("100", "Trying");
if (client_nat_test("2")) {
setbflag(6);
fix_nated_register();
force_rport();
}
if (!aaa_www_authorize("")) {
www_challenge("","0");
exit;
};
if (!db_check_to()) {
sl_send_reply("401", "Unauthorized");
exit;
};
consume_credentials();
if (!save("location")) {
log(1, "***--REGISTER: location save failed!\n");
sl_reply_error();
}
In case the consume_credentials() function was causing the fault, I
repeated my tests with that line commented out. However, the counter
is still going up.
There is no "ul dump" option in opensipsctl, but there is a "ul show"
function. It shows the correct information:
[root at centos6v log]# opensipsctl fifo get_statistics usrloc:
usrloc:registered_users = 3
usrloc:aliases-users = 0
usrloc:aliases-contacts = 0
usrloc:aliases-expires = 0
usrloc:location-users = 3
usrloc:location-contacts = 2
usrloc:location-expires = 1
[root at centos6v log]# opensipsctl ul show

Hi John,
As the statistic is know to work well, I suspect something strange
with your setup (like re-registrations are actually new registers).
So, in the same time, please check the content of user location via:
opensipsctl ul dump
Just to see the actual records.
Regards,
Bogdan

Hi Bogdan
Yes, I can confirm that registered_users shows the same value through
the fifo get_statistics request and the SNMP MIB value. The statistic
that appears to show the correct number of registered users is
usrloc:location-contacts
Here is the complete list of usrloc statistics on my test server
today
- only one UA is registered at the moment:
# opensipsctl fifo get_statistics usrloc:
usrloc:registered_users = 14
usrloc:aliases-users = 0
usrloc:aliases-contacts = 0
usrloc:aliases-expires = 0
usrloc:location-users = 14
usrloc:location-contacts = 1
usrloc:location-expires = 13
Sorry I cannot maintain the thread on this reply - I am only
receiving digests from this forum and have forgotten my login details
so cannot change it.

Hi John,
That stat is related to the internal statistic "registered_users"
provided by the usrloc module. Can you confirm that "opensipsctl fifo
get_statistics registered_users" gives thesame value as via SNMP ?

Bogdan

Using SNMPStats with version 1.6.2 of OpenSIPS, the value reported
for openserSIPRegCurrentUsers does not indicate the number of UA's
currently registered. It shows a value that is always increasing
over
time.
I am testing with 3 registered devices. There are three records in
the location table. However, openserSIPRegCurrentUsers now has a
value of
12 and it increments by 1 approximately every 20 minutes. I would
guess it is showing the cumulative total number of registrations,
not the current number of registered users.
