I debug this asterisk process with gdb + asterisk + pid
I found it will not break in for(){¡.} in asterisk.c ,look¡
for (;;) {
buf = (char *)el_gets(el, &num);
if (buf) {
if (buf[strlen(buf)-1] == '\n')
buf[strlen(buf)-1] = '\0';
consolehandler((char *)buf);
} else if (ast_opt_remote && (write(STDOUT_FILENO, "\nUse EXIT
or QUIT to exit the asterisk console\n",
strlen("\nUse EXIT or QUIT to exit the asterisk
console\n")) < 0)) {
/* Whoa, stdout disappeared from under us... Make
/dev/null's */
int fd;
fd = open("/dev/null", O_RDWR);
if (fd > -1) {
dup2(fd, STDOUT_FILENO);
dup2(fd, STDIN_FILENO);
} else
ast_log(LOG_WARNING, "Failed to open /dev/null to
recover from dead console. Bad things will happen!\n");
break;
}
}

You gave practically no details about your issue. Do you see any
interesting message in the logs? /var/log/asterisk/messages ?
Also note that many bugs have been fixed since 1.4.0 . Trying a newer
version (e.g: 1.4.18.1) is another option. There's a good chance that
that specific issue has been fixed since.
