Overload ESP8266-07

[Nowfalyahir]

Hello
I use your great project
And because I only need DMX output, I use this version
I faced a problem
After working for about 15 minutes, my ESP8266 disconnects for 5 seconds and reconnects to the software and continues to work.
I tested on 2 other ESPs, only one device has less disconnection
I tested the entire electrical system, there is no problem with the drop in voltage and current
After testing the module, I found out that the device gets overloaded after working and starts working again after restarting
Where do you think the problem could be?

it can be a software problem, for example it can go out of ram for some reasons. I suggest you to create a dedicated LAN/wifi domain withut other devices connected, to reduce the presence of other useless packets coming to ESP

It is exactly a software problem on ESP
I use the device's stand alone mode
Because in this way, there is only a stable connection between the laptop and ESP
And I don't know the reason for overloading the device
