10MB once no, but lets say hypothetically, if the dropbox api returned an error or wasn't available which denied your request but your script didn't account for it and it constantly kept making the request over and over and over. The 10mb would soon add up. Also, are you sure it wasn't something else, not the dropbox db script which could have caused problems?
