Hello
We experienced a failure on our kamailio (4.2.1+trusty), which required
a restart.
May 6 07:40:41 rtpproxy01 /usr/sbin/kamailio[5467]: ERROR: <core>
[msg_translator.c:2270]: generate_res_buf_from_sip_res(): out of mem
Afterwards we inspected all the settings to be using default, but at a
much higher level than an other older kamailio which runs much more traffic.
The big difference, is that this kamailio works with rtpengine. Does
that require more memory?
We also observed that the free memory is constantly falling on some
instances. They all started with 16MB but after 1½ day some are on 11.6
Is this normal behaviour that will find a natural level or is there
something bad going on?
We can also see that there are frags. Is that to be worried about, or is
this natural?

We use 4.2.1+trusty with these modules, is it possible that a newer
version has fixed some memory leak?
