使用Ryanmqtt软件包，连接EMQX服务器后，mqttThread线程硬故障，大佬们这是为什么？哪里的问题？如何解决？

使用RyanW5500和Ryanmqtt软件包，当连接mqtt服务器大概1分钟后，控制台提示mqttThread线程硬故障
连接成功后，如果立马发布或者订阅主题，直接提示线程硬故障，如果连接成功后什么都不做，等一分钟才提示线程硬故障
这是Ryanmqtt部分代码：

```c
#define RyanMqttHostName ("192.168.1.80") // 填写你的mqtt服务器ip
#define RyanMqttPort ("1883")               // mqtt服务器端口
#define RyanMqttUserName ("STM32")               // 为空时填写""
#define RyanMqttPassword ("STM32")               // 为空时填写""
	
	
int mqttConnectFun()
{
    RyanMqttError_e result = RyanMqttSuccessError;
    RyanMqttClientConfig_t mqttConfig = {
        .clientId = "RyanMqttTessdfwrt",
        .userName = RyanMqttUserName,
        .password = RyanMqttPassword,
        .host = RyanMqttHostName,
        .port = RyanMqttPort,
        .taskName = "mqttThread",
        .taskPrio = 16,
        .taskStack = 10240,
        .recvBufferSize = sizeof(mqttRecvBuffer),
        .sendBufferSize = sizeof(mqttSendBuffer),
        .recvBuffer = mqttRecvBuffer,
        .sendBuffer = mqttSendBuffer,
        .recvBufferStaticFlag = RyanTrue,
        .sendBufferStaticFlag = RyanTrue,
        .mqttVersion = 3,
        .ackHandlerRepeatCountWarning = 6,
        .ackHandlerCountWarning = 20,
        .autoReconnectFlag = RyanTrue,
        .cleanSessionFlag = 0,
        .reconnectTimeout = 3000,
        .recvTimeout = 11000,
        .sendTimeout = 2000,
        .ackTimeout = 10000,
        .keepaliveTimeoutS = 60,
        .mqttEventHandle = mqttEventHandle,
        .userData = NULL};

// 初始化mqtt客户端
    result = RyanMqttInit(&client);
    RyanMqttCheck(RyanMqttSuccessError == result, result, ulog_d);

// 注册需要的事件回调
    result = RyanMqttRegisterEventId(client, RyanMqttEventAnyId);
    RyanMqttCheck(RyanMqttSuccessError == result, result, ulog_d);

// 设置mqtt客户端config
    result = RyanMqttSetConfig(client, &mqttConfig);
    RyanMqttCheck(RyanMqttSuccessError == result, result, ulog_d);

// 设置遗嘱消息
    result = RyanMqttSetLwt(client, "pub/test", "this is will", strlen("this is will"), QOS0, 0);
    RyanMqttCheck(RyanMqttSuccessError == result, result, ulog_d);

// 启动mqtt客户端线程
    result = RyanMqttStart(client);
    RyanMqttCheck(RyanMqttSuccessError == result, result, ulog_d);
    return 0;
}
```

这是控制台刚连上时

这是等了一分钟后，控制台提示线程硬故障

提示这个就线程又硬故障了

后面我又加了一个CmBacktrace MCU错误追踪库，发现提示
Function[rt_mutex_take]: scheduler is not available
rt_mutex_take调度程序不可用
