ucos 异步线程操作lvgl时，出现内存溢出问题

static void GUI_Proc(void *p_arg)

    CppEntry();

    while(1)
    {
        OSSemPend(LvglTaskHandleMutex, 0, &g_lvglTaskHandleMutexErr);
        lv_task_handler();  
        OSSemPost(LvglTaskHandleMutex);

``这边是按键事件回调，按键按下后，会调用动画显示，然后在另外一个线程加载数据，数据加载完成后，另外一个线程发送事件结束动画
void CReagentSetupWnd::DefWindowProc(lv_obj_t* obj,lv_event_t e)
{
    if(obj == m_setupTab)
	{
		switch(e)
		{
            case G_EVENT_WAIT_START:
                {
                    if(m_oReagentModel.m_taskType == 1)
                    {
                        m_pWaitPromptDlg->m_strWaitText = "Delete operation in progress,\n please do not shutdown...";
                    }
                    m_pWaitPromptDlg->OnInitDialog();
                }break;
            case G_EVENT_WAIT_END:
                {
                    if(m_oReagentModel.m_taskType == 0)
                    {
                        DelayInit();
                        m_pWaitPromptDlg->EndWait();
                    }
                    else if(m_oReagentModel.m_taskType == 1)
                    {
                        ChangeWnd(WND_MAIN_MENU,1,0);
                    }
                }break;
		}
	}
}
这边是动画的初始化 
void CWaitPromptDlg::OnInitDialog(lv_obj_t* obj,lv_event_t e)
{
    CPopUpBaseDlg::OnInitDialog(obj,e);
    
    m_waitConntent = lv_obj_create(GetPopUpBaseObj(),NULL);
	lv_obj_set_size(m_waitConntent,LV_HOR_RES / 2,150);
	lv_obj_align(m_waitConntent,NULL,LV_ALIGN_CENTER,0,0);
    
    string t_strTitle = "Attention";
	AddTitle(m_waitConntent,t_strTitle);

    lv_obj_t * arc = lv_arc_create(m_waitConntent, NULL);
    lv_arc_set_bg_angles(arc, 0, 360);
    lv_arc_set_value(arc,80);
    lv_obj_set_size(arc, 50, 50);

    m_tipsTextObj = addLabel(m_waitConntent,NULL,m_strWaitText.c_str());
    
    lv_obj_align(m_tipsTextObj,NULL,LV_ALIGN_CENTER,0,30);
    lv_obj_align(arc,m_tipsTextObj,LV_ALIGN_OUT_TOP_MID,0,-10);
	
    lv_anim_t a;
    lv_anim_init(&a);
    a.repeat_cnt = LV_ANIM_REPEAT_INFINITE;
    lv_anim_set_exec_cb(&a, (lv_anim_exec_xcb_t)lv_arc_set_rotation);
    lv_anim_set_values(&a, 0, 360);
    lv_anim_set_time(&a, 1000);
    lv_anim_set_var(&a, arc);
    
    //lv_anim_set_ready_cb(&a, end_cb);
    lv_anim_start(&a);
    printf(" Wait prompt Dlg lv_anim_start \r\n");
}
这边是另外一个线程的处理
void CReagentSetupModel::ThreadFunc()
{
    printf("=====Satrt CReagentSetupModel ThreadFunc m_taskType %d  m_notifyObj %x======\r\n", m_taskType, m_notifyObj);
    switch(m_taskType)
    {
        case 0:
          { 
              if(m_notifyObj != NULL)
              {
                lv_event_send(m_notifyObj, G_EVENT_WAIT_END, NULL);
              } 
          }
          break;
        case 1:
          {
              if(m_notifyObj != NULL)
              {
                lv_event_send(m_notifyObj, G_EVENT_WAIT_START, NULL);
              } 
              
              m_pData->DelTest(m_curTest);

              if(m_notifyObj != NULL)
              {
                  lv_event_send(m_notifyObj, G_EVENT_WAIT_END, NULL);
              }
          }
          break;
    }
    printf("=====End CReagentSetupModel ThreadFunc m_taskType %d ======\r\n", m_taskType);
}
线程执行完成以后，发送事件，通知lvgl结束动画调用，并刷新屏幕，具体函数如下
void CWaitPromptDlg::EndWait()
{
   	m_retValue = value;
       
    ReleaseOBJPtr(m_curDlgObj);
      
	lv_event_send(m_notifyObj, m_notifyEvent, NULL); //阻塞式调用

	m_retValue = -1;

	m_notifyObj = NULL;
    
    printf(" Wait prompt Dlg OnClose \r\n");
        
    if(LvglTaskHandleMutex != NULL)
    {
        OSSemPend(LvglTaskHandleMutex, 0, &g_lvglTaskHandleMutexErr);
    }    
    
    lv_obj_invalidate(lv_scr_act());
    
    if(LvglTaskHandleMutex != NULL)
    {
       OSSemPost(LvglTaskHandleMutex);
    }
    printf(" Wait prompt Dlg lv_obj_invalidate  End\r\n");
}
