ESP8266 Community Forum

I am new in the forum and in the esp so I apologize for any noob mistakes.
I have an esp8266-01. My project is running multiple requests from server through esp82266. However in random occasions the esp8266 will restart on its own..I manage to recover from this but sometimes after it restarts it works for a little bit of time and then it restarts again and i get this in the second restart and then no response from esp

1) Give your post a more descriptive subject line
2) If you refer to a project that is having problems, describe the project
3) Search the forums to see if the question has been similarly posed in the past. Maybe the previous answer will assist.

Your log shows that you are timing out because of the Watch Dog Timer (WDT). This could be for a myriad of reasons and without knowing more about the nature of your application, there isn't much to offer other than search the forum on this phrase (watch dog timer) and see what others may have said. If you wish to post back with more details, then we can look further.

Okay thanks for the tips.
My configuration is Arduino with the esp and one temp sensor (dht11).
Every 1 min it measures the temperature and sends it to my web server through an http request(get) locating in my raspberry.
Also every 30 sec it sends an http request(get) to get one value from a txt file in my web server(raspberry).
It was running fine for about 1-2 weeks...However in the last 2-3 days it gives that error without changing anything in the configuration or in the code.
