Problem Description

Hi, I have developed an application to post http req at regular intervals to a remote server. This application uses esp_http_client.c library. After few iterations of http post req, I see "Allocation Failed" Error and http req fails.

Expected Behavior

http req should post successfully in all iterations

Actual Behavior

http post req fails due to allocation failed err from http_client

Steps to repropduce

step1-
...

// It helps if you attach a picture of your setup/wiring here.

Code to reproduce this issue

// the code should be wrapped in the ```cpp tag so that it will be displayed better.
#include "esp_log.h"

void app_main()
{

}

// If your code is longer than 30 lines, GIST is preferred.

Debug Logs

Debug log goes here, should contain the backtrace, as well as the reset source if it is a crash.
Please copy the plain text here for us to search the error log. Or attach the complete logs but leave the main part here if the log is *too* long.

Other items if possible

[ ] sdkconfig file (attach the sdkconfig file from your project folder)
[ ] elf file in the build folder (note this may contain all the code details and symbols of your project.)
[ ] coredump (This provides stacks of tasks.)

@VallariTrivedi Can you share snippet of how you are sending http post req at regular intervals? It seems likely that you are invoking esp_http_client_init() API multiple times without calling esp_http_client_cleanup() API at the end of each iteration of request, which is resulting in "Allocation failed" error.

@VallariTrivedi Could you help share if any updates for this issue? Thanks.

VallariTrivedi commented 5 years ago

@jitin17 I added esp_http_client_cleanup() to the calling API. This solves "Allocation Failed" error.
