Libmodbus supports RTU host, slave and modbustcp. If they are used in RTOS at the same time, are they mutually exclusive?

I'm at RT_ Thread is used at the same time, but the system will crash after running for a long time. The prompt position is "RT thread / SRC / IPC. C: 929, RT_ mutex_ release；/packages/libmodbus-latest/examples/modbus_ tcp_ test.c:224 ，FD_ SET(server_ fd, &readset);“

I wonder if it is because they are not mutually exclusive, and there is a conflict between modbustcp and RTU?
