vrf Reverse array

Hi Everyone,
I have a VEE Pro program in which I query a moderately large number(10-20) of different units over an RS-485 communications line. Between these units there are two or three different I/O objects with varied settings (8-bit word, no parity; 7-bit word, no parity and 7-bit word, even parity). To send to these units, I create an array of all the units to send to and use a loop to cycle through all of them repeatedly.
What I am finding is that this will work for some amount of time, anywhere between 12 and 48 hours but will inevitably cause VEE to freeze at a Direct I/O object. After this freeze, VEE must be totally shut down and will lock up in the same way any other time a Direct I/O object is used until the computer has been restarted.
I was wondering if anyone has encountered something similar in the past or have any ideas as to why this keeps happening. Any help is greatly appreciated.
