"Internal Interface suddenly freezes"<br>
</p>
<p>I have the feeling that lot's of presence messages make internal
profile stuck. This happens under high load with a lot of presence
involved. Suddenly Freeswitch internal profile stops responding
and after a while (some minutes) it responds again. During that
time, no register requests are answered at all. Only a few
XML-Curl requests are sent to the server, but they do not contain
the user info (which are needed for registrations) and are related
to mod_voicemail.c etc.</p>
<p>Looking at your problem: Sometimes, even long before the above
happens, some presence messages get lost. Not all of them, but a
high percentage.</p>
<p>The above github link shows an enhancement (better sql query) in
the presence module, which fixed this for us.</p>
<p>Before that, we made a process, which captured the SIP NOTIFY
packages for "BLF up" statements and resent them via ESL. This
also worked pretty well as a workaround.<br>
</p>
<p>Best regards</p>

<div> Looking for some help with BLF in Freeswitch. Randomly for
few users BLF indicator for parking and shared lines stops
working. <br>

<div>Rebooting the phone fixes the problems for some time and
then again it stops working. <br>

<div>We have FS 1.10.6 <br>
</div>
<div>Approx. 500 Users Registered (most of them registered
remotely from different networks) <br>
</div>
<div>1000 Contacts (Multiple registrations) Using Call Parking
and Shared lines, most phones subscribe for BLF to monitor the
calls on shared line or parked calls. <br>
</div>
<div>System Details: VM with 12 GB Ram and 8 Core CPU. Using
Postgres for Core Data and profiles. <br>
</div>
<div>Max 40-50 calls. <br>
</div>
<div>Sometimes I notice high CPU on this server, while on other
servers with no shared lines and no BLF, Virtual machines
handles 100+ calls and 700 users. Anyone could provide any
suggestions/hints to help troubleshoot this. Is this too much
for one server to handle? Is BLF too complicated? <br>
