Hi I am working on some can project recently,it was a little device (MCU) receiveing the terminal PDO, it works fine in the few hours but i find out that I can't transmit any PDO to my device (terminal still can receive the PDO from device) andit won't show any error message but if we restart the program it shows this message

You can try experimenting with the txqueuelen parameter on the SocketCAN interface. I've had success to increase reliability on a Raspberry Pi by setting it to higher values like 500 or 1000.
