Hi All,
Kamailio 3.1.2 terminated with signal 11, segmentation fault, in the init_mod_child function at sr_module.c file. This problem occurs only when I try loading the loadbalance.so module, it was written by me.
Someone Can help me to understand why this segmentation fault was generated? There are two other module written by me and this problem doesn't happen.
Kamailio's trace:
