用GUI做个RTC实时时钟界面，运行一段时间后，界面和时钟指针就不会刷新了，任务死掉了一样

创建了三个任务，LED闪烁，GUI时钟界面和触摸。GUI时钟界面不会刷新之后，其他两个任务还能运行。
没有用RTC中断，用了之后界面根本就不会显示。
网上看了，说是GUI_Delay();问题,我的GUI_X_Delay如下：
OS_CFG_TICK_RATE_HZ=1000u;
void GUI_X_Delay (int period)
{
OS_TICK ticks;
OS_ERR err;
ticks = (period * 1000) / OS_CFG_TICK_RATE_HZ;
OSTimeDly((OS_TICK)ticks,OS_OPT_TIME_DLY,&err);
}

跟系统时钟一致，但是如果用GUI_Delay（30）,四十几秒后界面就死掉，如果用GUI_Delay（500）,一分多钟后界面就死掉。
死掉是界面不刷，时钟指针一直停着。代码如下，求大神解决啊
