[已解决] ESP32 MQTT发送数据失败导致重启

[langjitianya]

我在用ESP32-C3 MQTT通信时遇到发送数据出错而重启的情况，谁能帮忙解决一下问题。这是报错导致重启的日志：
I (134496) MQTT: MQTT_EVENT_ERROR
I (134496) MQTT: Last errno string (Success)
E (134496) MQTT_CLIENT: Error write data or timeout, written len = 0, errno=0
Guru Meditation Error: Core 0 panic'ed (Store access fault). Exception was unhandled.

看起来是程序挂在mymqtt.c文件里，能否提供简单的示例代码和提供你使用的 IDF 版本号。

我觉得问题可能是网络不好，数据发送失败导致哪个API用了非法的指针导致重启的

[langjitianya]

问题也不是每次都必定出现的，有时候测试几十分钟才会有这个问题

[langjitianya]

我找到问题了，在MQTT断开或者出错的情况下把删除任务函数去掉就不会报错了，重连功能正常
