Unable to find the exact reason for the above problem. Pl advice
It apppears to me that you get some kind of timeout, and the connection is closed, but I might be proven wrong. Nevertheless, you should handle such cases, as this may happen even in the most critical high availability solutions, for instance if a SQL Server Cluster is failing over. Applications should be able to reconnect automagically.
