Multiple errors in log when connecting multiple machines#28

Hello,
I am testing the MachineJob sample project to connect several machines to a local Modbus server that I have for testing, all the slave channels work correctly, but when starting the program, some machines seem not to respond, or they respond but not all the parameters.
I am testing this example because before this I made a code where I asked again to the same machines but the memory consumption was rising until consuming the total available RAM memory.

This is the configuration I use for the test project, the map is the same for each machine.
