I have a new installation of SharePoint 2013 Enterprise, and am consistently having an issue with adding list items to any list I create. I can however upload documents to document libraries. When I attempt to add a list item, I get the following error (also seen in attachment): "The server was unable to save the form at this time. Please try again.". I found a couple of articles about this error but none of those solutions helped. The front end server has no shortage of RAM, but I did try restarting the "SharePoint Search Host controller" service anyway per one of the articles. I also haven't been able to pinpoint any relevant errors in the logs.
