S32K144 is always stuck after a period of time

[bearman_m]

I use many "function call subsystems" to send and receive messages from 3 can ports. 

But I always encounter a strange phenomenon. The MCU works perfectly in a short period of time, and the transmission and reception of the messages are also normal, but after a period of time, the program is completely stuck and cannot receive or send information. I don't know where the conflict is, and I look forward to your answers.

Thank you very much!

You are using FCAN blocking model type communication in parallel of 3port,in that any one of the communication receiver not responding means it will struck. And it willl make issue in the next two communication  as per the last image block. Check communication signal and toggle one gpio for verify the communication struck happen by blocking communication.

Thank you very much for your answer. I can probably understand what you mean, but why does this module get stuck when no information is sent?

If I have to use this module, is there any solution to prevent the program from getting stuck?
