server log errors for connection

I have a lot of the server log errors:

But all the transactions seem to be processed successfully after I changed the retry count from 0 to 10. Are the server log errors important for this case? Can I suppress the server log errors if the transactions were processed successfully? (I am using mirth 3.0.1.7051) Thanks
