<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></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>

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