Hello Daniel,
Thanks for reply. I found the problem. it is about ACCDB. when i active
WITH_ACCDB , after t_relay function ,dialog_ng is crashed. I added simple
cfg. I try to change flags to fix problem. bu i think it isn't about it.
Kamailio V2.4.2 Centos 6.6 64 bit Linux ims-kamailio.localdomain
2.6.32-504.12.2.el6.x86_64 #1 SMP Wed Mar 11 22:03:14 UTC 2015 x86_64 x86_64
x86_64 GNU/Linux
How to debug it to fix this problem? When i increase debug level , cant see
anything because of imuxsock.
Thanks.
