<p class="MsoNormal">I’m in the process of moving approx. 100
Kamailio/Media Proxy (AG Projects) servers to
Kamailio/RTPEngine. I have all the functionality in place and
I have a handful of servers in production. I’m trying to
monitor the RTP engine (using Munin) and I’m graphing the
values returned from the RPC command <span
style="color:black">
rtpengine.get_hash_total. This value is slowly increasing
over time and I’m trying to find out if this is something I
should worry about. I want to make sure that sessions are
not being left open and therefore the software will
eventually run out of ports. To give some values, if I make
100 calls the call will be around 25 after those calls.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black">From all other
tests I have done including a check through the verbose logs
I can see the sessions are being closed at the end of the
calls.<o:p></o:p></span></p>

with this at all or does anyone possibly have any better
ideas?</span></p>

<br>
The size of the hash table does not necessarily directly correlate
with the sessions rtpengine itself has open. Normally it should, but
it's possible for rtpengine to close a session with the entry
remaining in the hash table, or vice versa.<br>
<br>
To get a better idea of how many sessions rtpengine actually has
open, check out it's CLI interface or the related control script
(rtpengine-ctl).<br>
<br>
As for the hash table itself, AFAICS entries are deleted when the
_delete method is used. Otherwise they stay in memory until the
timeout is reached, defaulting to 1 hour. (They're only actually
deleted after the timeout if encountered while processing the hash
table at some point.) If you don't see the hash table decrease in
size, it's probably not calling the _delete method properly.<br>
