osal发送带有讯息任务问题 ！

TI好：

我用串口来控制代码做OSAL带有讯息任务的轮循动作,

以下为简单的代码描述:

if ( events & SYS_EVENT_MSG )
{
    uint8 *pMsg;

if ( (pMsg = osal_msg_receive( simpleBLECentral_TaskID )) != NULL )

    ProcessOSALMsg( (osal_event_hdr_t *)pMsg );

// Release the OSAL message
VOID osal_msg_deallocate( pMsg );
}

void ProcessOSALMsg(osal_event_hdr_t *msg){

   switch(msg -> event)  

      case MyEvent:

       Myfunction((myStructData_t*) msg);

      break;

}

void Myfunction((myStructData_t*) msg){

switch(msg->Myevent)

case seriaPortlEvent:

   myStructData_t *receive;

   receive = (myStructData_t*)osal_msg_allocate( sizeof(myStructData_t));

   receive->hdr.event = MyEvent;

   receive->Myevent = seriaPortlEvent;

   osal_msg_send( TaskID, (uint8 *) receive ); //轮循

  (void)HalUARTWrite(0,"1\n",2);

}

问题： 

想要的结果是会一直打印“1” , 但代码每次运行到一半都会停止，需要重新用串口送命令才會繼續打印"1",

这是内存的问题吗？但每次都有运行到VOID osal_msg_deallocate（PMSG）才对阿

求解

有人遇过相同问题吗？
