Hello,
did you get a core file? If yes, send here the output for 'bt full' taken in gdb.
Cheers, Daniel

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
