In my project, my program have not stop, but the chip is reset, and the log is :rst:0x8 (TG1WDT_SYS_RESET). Please give me an answer

We know wifi is critical for working - couldn't we somehow dedicate wifi to run on first core and user program on another?
Is rtos mixing first and second core for all task including user tasks and wifi tasks?

Assign a task to specified core with xTaskCreatePinnedToCore

Also, do you get just a watchdog reset with nothing preceding it, or do you actually get a panic handler message?

In the task handler created by xTaskCreate,the code:
...
ESP_LOGI(TAG, "ESP32 start send data...");
while(1) {
err = netconn_send(udpclient_conn, udpclient_sendbuf);
}
...
each time after the handler netconn_send have excuted, there will be the a chip reset,the log is :

then the chip will be reset again, I don't konw how to solve this problem???

Do you get the same result if you enable "Run FreeRTOS only on the first core" option in menuconfig (component config > FreeRTOS)?

Using ESP WROOM32 SDK and esp-idf 4.2, esp module repeatedly restarting by displaying as rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) in the terminal window. This problem is causing when i tried to initialize a larger data array in the firmware. So kindly let me know how to use a large array (unsigned int) without any error as shown in this screenshot.

Suggest you post your code, simply initializing a large array should not lead to this.
