Vc4 keeps crashing
My core 4 keeps crashing many hours in to a print. It gets a significant way through a 2 day print and keeps just becoming non functional. Klippy log doesn’t show any klipper errors. I have to restart the printer to gain connection as I can’t ssh or browse the mainsail interface when this happens. Does anyone have any suggestions on what to check as I’ve currently wasted 5 kg of filament trying to solve this

Additional information. The bed and hotend stop staying warm movement ceases and fans still run when it happens
this is the end of var log messages

Appears a usb device disconnected. Just my 2 cents Could be the EBB42? Bad cable.
