Toolboard or mcu problems

Hi, i have custom build with RatOS. Setup: IDEX Kraken v1.0 EBB42 v1.2 rpi4b 4GB VAOC ect Machine is working most of the time but sometimes i have weird problems with communications, im using like 300-500mb gcodes most of the time and it can cause some of the problems... RPI and kraken are well cooled, EBB are in the chamber, they are max 78-80C, on other printers they were reaching 100 and still working, so its weird issue. Printer is quite fast so just maybe some of the electronics can't keep up? Below is klippy.log from last event and its the photo of the screen. Ive used official supported 64GB microsd card, and rest things so just need some help to make it work again...maybe to high gcode resolution? Maybe arahne is using to much things and everything just cant catch up... I wasnt also updating RatOS form the past 2 months, so if there are some big updates with optimizing settings just let me know. Thanks!
