<tt>Hi, Stefan!<br>
<br>
Indeed, there is no "Deleted" state in the db, not even in
opensips' memory.<br>
Can you paste the records of two bindings that should not be
there?<br>
Since you are using db_virtual, are you experiencing any failover?<br>
<br>
Best regards,<br>

<div>Hi Razvan,<br>
</div>
thanks for replying<br>
<br>
</div>
I notice that the bindings remain in the DB for a while (at
least > 5min), sometimes they are deleted immediately (as
I would expect), some other times they remain in the table.<br>
</div>
So reregistering returns 200OK (2 bindings or 3 , increasing).
Re querying the DB shows an increment of equal bindings for a
client until the limit is reached for max amount of
registrations in the config (10 by default I believe?). <br>
<br>
If I decrease that setting lets say to modparam("registrar",
"max_contacts", 2) then I will very soon get an error reply
back. Note that this behavior (increment of bindings) is not
consequently observed (it is intermittent).<br>
<br>
</div>
The DB setting in the config (config was attached to original
email as well as pcap) is:<br>
<br>
#### USeR LOCation module<br>
loadmodule "usrloc.so"<br>
#modparam("usrloc", "nat_bflag", "NAT")<br>
modparam("usrloc", "db_mode", 3)<br>
modparam("usrloc", "db_url","virtual://pmset")<br>
<div>
<div>
<div>
<div><br>
</div>
<div><br>
</div>
<div>You mention a '<i>Deleted</i>' state, but I was
unable to find that flag . Should that be in <i>opensips.location</i>
table?<br>

<br>
Are you saying that the Contacts "leak" in the database
(they are never deleted), or that they are not deleted
immediately after the client is deregistering (but they
are a bit later)?<br>
<br>
What is the db_mode setting[1] you are using for the
usrloc module? Also, note that the Contacts might still
be present in the database after they are deleted, but
with a Deleted state. If that's the case, this is
perfectly fine.<br>

<div>Hi there,<br>
</div>
I noticed that opensips 2.2.5-1
intermittently does NOT flush the
contact when the client is
deregistering.</div>
<div>It is reproducable with multple sip
clients. opensips 2.3 also suffers from
this issue.<br>
</div>
<div><br>
</div>
When I check the mysql database backend I
can see that the entry is table
opensips.location is not consistently
deleted.</div>
<div>It works for several times and the
subsequently it does not flush the contact
showing two bindings the next time the
client is registered.</div>
<div><br>
</div>
<div><br>
</div>
I can unfortunately not monitor the sql
queries because opensips is using tls for
secure transmission.<br>
</div>
I use mysql as backend and the config is
attached as well as the local wireshark trace
