Hello,<br>
<br>
that backtrace is from shutdown, if you don't have another core
file, then the initial one was overwritten. You have to enable one
core per process. In most of system it is:<br>
<br>
<meta http-equiv="content-type" content="text/html; charset=KOI8-R">
<pre class="code">echo "1" > /proc/sys/kernel/core_uses_pid</pre>
You have to reproduce the issue again and get the backtrace from all
core files.<br>
<br>
Cheers,<br>

<pre wrap="">Dear Support,
I am having an "out of memory" problem while using kamailio with SEAS
module.
After using Kamailio with the SEAS module for few hours with a high
load , I am getting "out of memory" error that I believe is caused
from a memory leak.
I would like your help interpreting this error.

As you can see above , the output of the SEAS module is not showing
(pid
31200)
Moreover , I can see that the real_used value in the kamcmd
core.shmmem keep on increasing , and free decrease until I finally
get an error "out of memory"
When my SEAS client exit the output of kamcmd core.shmmem :
{
total: 33554432
free: 16273440
used: 1787296
real_used: 17280992
max_used: 33553520
fragments: 8098
}
The traffic is a simple SIP MESSAGE from a seagull simulator, with a
200OK reply from my SEAS client.
I appreciate your support,
Thank you in advance,
Ziad Habchi
