ESP32 reboot after some 100-300-times web page loading (using ESPAsyncWebServer & AsyncTCP)

[Skrivo]

Hello experienced people!
I am not very experienced and I have an issue not able to solve by myself.
My setup:

• Arduino 1.8.15
• Arduino core for the ESP32 (version 1.0.6)
• latest library ESPAsyncWebServer (me-no-dev)
• latest library AsyncTCP (me-no-dev)
• ESP32 Dev Module

Micro_EVSE_3_WiFi_Charge_Control_v1.0k.zip

The attached Arduino ESP32 code for web server using web sockets works well on ESP32 but after entering (loading or even just reloading) the main web page some 100 to 300 times (random) the ESP32 restarts itself. It doesn't matter if I am connected using Soft AP or the ESP32 is connected to local WiFi network. If I am not reloading the page then it never reboots, it works without a single issue for days.
I get the following error information on the serial monitor:

So, the error is repeatable. ESP32 Exception Decoder lists the following:

As I am not super specialist this Exception Decoder results don't tell me much.

I don't know where is the issue but I suspect those two otherwise superb libraries: ESPAsyncWebServer & AsyncTCP
Maybe it is also something wrong in my code.

Please help me!

To: me-no-dev or anybody else: you can contact me directly to my e-mail fusionseeker@gmail.com if you have a reliable solution - I also have available some funds for a reward :)

Thanks,

Dejan

I have a similar issue, but it crash and reboot more frequently, randomly.
It always happen for the same page, not the other ones that always load perfectly.

That page probably needs more ressources but is only 560kb, like the other ones that never cause crash. But loading this page is more ressource intensive : reading data points from a csv file to display in chart.js

Here is the log:
