title: Error while creating task: The server was unable to save the form at this time. Please try again. (SharePoint 2013)
body: <p>I get the following error while saving a task inside task list:</p>
  
  <p><em><strong>"The server was unable to save the form at this time. Please try again."</em></strong></p>
  
  <p>I tried <strong>restarting "search service host controller"</strong>.</p>
  
  <p>The server has <strong>8 GB</strong> RAM and according to task manager, 6.67 GB is being used.</p>
  
  <p>I logged into the site with user which is the owner of the site. I tried creating tasks from client as well as the SharePoint server itself. Same error is shown in both the cases.</p>
  
  <p>How do I find information on the exact problem that is causing the error? What are possible solutions?</p>
