MTA application Hangs

Hi,

I have small MTA application which calls opcode PCM_OP_TEST_LOOPBACK.  But when i run this application,  pin_mta_worker_exit function is not called which make the application hangs.

Below are my configuration

- - children        3

- - per_batch       10

- - per_step        1

- - fetch_size      10

Code snippet.

#include <stdio.h>

#include <time.h>

#include "pcm.h"

#include "pin_errs.h"

#include "pinlog.h"

#include "pin_mta.h"

#include "pin_cust.h"

#include <unistd.h>

#include <sys/syscall.h>

#include <sys/types.h>

int   runs = 1;

static int64 pd  = 948365;

PIN_EXPORT void

pin_mta_init_search(

    pin_flist_t  *app_flistp,
