title: Attempted to read and write Protected memory
body: <p>We recently moved our application from Windows server 2003 to Windows server 2012. Application has two components-- one is MVC and other one is simple ASP.NET with aspx pages. 
  Application is working fine but sometimes we receive-- Attempted to read and write protected memory . This is often an indication that other memory is corrupt error. </p>
  
  <p>When I checked Event Viewer for the error, below is the exception:
  Exception information: 
      Exception type: HibernateException 
      Exception message: Creating a proxy instance failed </p>
  
  <p><strong>When we get this error, we usually recycle app pool and issue gets resolve. Need your inputs for long term fix</strong>.</p>
