Environment

• Development Kit: ATOM PSRAM(M5Stack)
• Kit version (PicoKit): V3
• Module or chip used: ESP32 PICO V3 02
• IDF version esp-idf-v4.4
• Build System: idf.py
• Compiler version (run xtensa-esp32-elf-gcc --version to find it): // 1.22.0-80-g6c4433a
• Operating System: Windows

Problem Description

Hello, i have started HTTPS client(async mode) according to examples. After a few minutes of working console prints that task WDT triggered and back trace info. when i disable hardware MPI it seems to works.

Expected Behavior

Works, if i disable hardware MPI form MBEDTLS config

Actual Behavior

Task WDT trigger and core hung

Steps to reproduce

Disable hardware MPI

Code to reproduce this issue

esp_http_client_config_t config = {
.url = "https://portal-rsig.ge/dev/",
//.path = "",
//.keep_alive_enable = false,
.method = HTTP_METHOD_POST,
.event_handler = _http_event_handler,
.crt_bundle_attach = esp_crt_bundle_attach,
.user_data = local_response_buffer, // Pass address of local buffer to get response
.is_async = true,
.timeout_ms = HTTP_REQUEST_TIMEOUT, //3000
};

    	    esp_http_client_handle_t client = esp_http_client_init(&config);
    	    esp_http_client_set_header(client, "Content-Type", "application/json");

		    do {
		        err = esp_http_client_perform(client);
		    }while(err == ESP_ERR_HTTP_EAGAIN);


		    if (err == ESP_OK) {
		        ESP_LOGI(TAG, "HTTPS Status = %d, content_length = %d",
		                esp_http_client_get_status_code(client),
		                esp_http_client_get_content_length(client));
		    } else {
		        ESP_LOGE(TAG, "Error perform http request %s", esp_err_to_name(err));
		    }
		esp_http_client_cleanup(client);
