  Using ESL found a memory leak problem
   valgrind --tool=memcheck --leak-check=full ./myprog

   Part of my code is as follows

bool CRBT::Route() {
string data = "ringback=file_string://";
data.append(FileName);

esl_execute(handle, "set", data.c_str(), NULL);
return true;
}

The OS version is Centos x86_64 6.3
The Freeswitch version is 1.2.13

Thanks for your help.
