Previous message is accidentaly sends itself.

The piece of code I posted in previous message sends message to node to try
find out if somebody connected to it, the next what I have to do is receive
responce, and I am trying to do it like that:

if (NgAllocRecvMsg(csock, (struct ng_mesg **)&ugetsas.reply, NULL) == -1) {
            syslog(LOG_ERR ,"check_and_clear(): Error receiveng responce
from ksocket %s\n",strerror(errno));
            ShutFanout();
            return EXIT_FAILURE;
}

And program stuck on this command, the debug information  I receive :

Sep 25 16:29:38 freebsd-test relaying-ng: RECEIVED RESPONSE:
Sep 25 16:29:38 freebsd-test relaying-ng: SOCKADDR: { fam=32 len=16

Sep 25 16:29:38 freebsd-test relaying-ng: NG_MESG :

Sep 25 16:29:38 freebsd-test relaying-ng:   args   inet/10.128.0.44:34817

So it seems all ok, but I can`t understand why is it hangs.
Any help appriciated.
Sorry for bad english.
