As I am working, adding content pages, to my DNN 4.3.7 web site I often see a few exceptions. After a minute or two I can perform the desired operation. When I look at the log I see exceptions. Not all are the same exception. I will attach one here. Many say page is "unavailable". Is this a setup issue, normal operation for DNN or a bug?  When I am actively editing content, exporting templates etc. I see about 3 per hour. Since almost nobody else is viewing the site the portal isn't being hit very hard.  The site is hosted at GoDaddy and is medium security.
