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.
The output of kamailio –v is :

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
