BeagleBone Black - Modbus TCP Communication Issues

Hello guys @Middleware & OS I am working on an industrial automation system using a BeagleBone Black running Embedded Linux. The system needs to monitor and control a process using multiple sensors and actuators over a Modbus TCP network. However, I encounter an issue where the BeagleBone Black intermittently loses communication with some of the Modbus devices(temperature sensors and relay). Has anyone @everybody encountered such a situation before, what did you do to resolve it and can you refer some documentation for me to go through.
THANKS IN ADVANCE!.
