HI i am using CANBUS in ESP32 for such a long time and i made some modifications such BUS-OFF will get recovered, but after sometime one of my ESP keeps receiving same messages continuously. This issue persist even ifi disconnect other ESP s from bus and connect back without switching off the affected ESP which is receiving messages.

If i hard reset the ESP then it starts working properly. What could be the issue?

Could you describe what modifications you've made?

Could you verify (e.g., with a logic analyzer) whether the same message is not actually being sent repeatedly on the bus?
