Each page reload takes the free heap down to zero
When I run the demo code, each reload causes the freeheap value to decrease by 1-2 kB. When the value gets close to zero (15x reloads approximately), it causes a loss of function and then eventually a restart of the ESP8266 with an OOM error. Everything can be seen in the picture. How to solve this problem?
