Thanks. "--RETRIES" returned a value of 6 which I guess is the default. I changed the setting to 1 and now both units are sending and receiving messages from each other only one time. This appears to do the trick.
So basically, with a setting of 1, I'm guessing the sending unit doesn't require an acknowledgement from the receiving unit in order to consider the job complete.
Now, to experiment with that theory, I will change the "--RETRIES" setting to 30 and see if I get the message 30 times or if there is in fact an acknowledgement at some point.....
Wow! Interesting result... The message went through on the first try and an acknowledgement was received. The message ended up being sent only one time. I tried this on both units with the same result. I didn't expect that happen.
I'm a bit puzzled and can't figure out why I would get that result on
"--RETRIES 30" when I had such a different result at the point "--RETRIES" was at the default setting of 6.
.... hmmm my working theory now is that maybe changing the "--RETRIES" setting somehow reset something in the system or maybe forced it to recognize that parameter setting where it maybe wasn't seeing it before. Or perhaps there is some sort of logical connection within the programming where "--RETRIES" and the message acknowledgement loop have some sort of dependency or inter-relationship in the coding. If that is the case, maybe changing the Retries setting caused the acknowledgement loop to reset somehow.
Anyway, that's all speculation and probably irrelevant. The good news is we got it to work! I really appreciate your suggestion. It seems to have cleared up whatever was causing the problem.
Have a great day!
