[valmik thakar]

hi,
we made a project based on esp8266(ESP-EROOM-02).
we use free RTOS sdk version 1.2 and use 4 threads of 512 byte each.
I got issue like on multiple request from http after sometime(random time) board is reset due to exception reset.
i don't get why this issue comes.
what is reason for get exception reset.

plz any one help me for this if know about it.

Hello Valmik,

You mentioned reset cause 2 and said that you get "exception reset". Did you mean that you are getting an exception and after that a reset?
You may find reset cause 2 if the chip is being reset by a low voltage on the reset pin. This is usually a circuit design issue.
Please post the UART log data if possible.

and how can i solve it please can you tell me about that.
and UART logs are enable but i don't got any conclusion form UART logs.
and in project we use GPIOs, timers and flash memory and tcp protocol mainly.

If nothing is clear from the logs, I suppose that memory leaks might be a probable cause. Are you using more than 512 bytes of memory in any thread?
Please narrow down the task which is causing the problem by running them individually.
