title: Error: Microsoft.HostIntegration.SNA.Session.SessionException: The underlying SNA session failed. The application must release the session
body: <p>I have a .NET application that uses Microsoft Host Integration Server 2016 to get data from an IBM mainframe computer. The application is setup to run on a schedule every hour to process a number of transactions. For each transaction, it connects to the remote mainframe, login, get the data, and then disconnect.
  I sometimes get the error: &quot;Microsoft.HostIntegration.SNA.Session.SessionException: The underlying SNA session failed. The application must release the session&quot;. Would appreciate if anyone has experienced with this error and let me know how to handle it?</p>
  <p>Thanks</p>
