I tried to reproduce this problem but was not successful. Are you using buttons or LED's? If buttons, what is the mechanical action set to? If it is set to Latch I would suggest trying Switch.
Another option is to move the server to another networked machine. If you do you will have to change the URL's for the data items.
Lastly, you might try reinstalling datasocket. The latest version can be downloaded form:
