IIRC, if you don't set:<br>
<br>
modparam("pua_dialoginfo", "override_lifetime", 14420)<br>
<br>
The value is taken from max dialog duration. Can you try
without this parameter? The parameter should be used only if
you want to overwrite the dialog module value.<br>

<p class="MsoNormal"><span style="color:#1F497D">Hi Daniel,</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">Sorry for the
delay in replying. I’ve attached blf.cap which shows the
“light stays on” scenario. You’ll see that the final
NOTIFY (packet 43) is a “confirmed” rather than a
“terminated” as per the PUBLISH (packet 41) that
triggered it.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">I’ve also
attached presentity.txt which is the contents of the DB
before the pcap was taken.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">With regards
to your question about the light going out after the
entries in the table have expired, this does happen
automatically. As soon as the table drops down to being
empty (it takes a couple of minutes to fully clear), the
light goes off. Subsequent calls will work correctly with
BLF until it eventually stops working and the whole cycle
repeats.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">I have
repeated the test with subs_db_mode 0 and the same results
occur. This is, in fact, the state it was in when the
attached pcap was taken.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">Do you think
the problem is in the cleanup of the data or in the way
the active dialog is matched against the set of data in
the table? Happy to prod through the code with gdb if you
can point me in the direction of where to start looking.</span><o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Can you get
a pcap for a case with the new config? Being traveling, but
maybe I get a chance to look at it soon.<br>
<br>
Reading quickly on some docs, I noticed that subs_db_mode=3
and notifier_proceses=0 rise a conflict:<br>

Can you try with subs_db_mode=0 and see if works different?<br>
