CAUSE:
This is happens because a firewall in between Strategy Web and Strategy Intelligence Server times out all the TCP/IP connections after a period of inactivity between Web Server and Intelligence Server.
ACTION:
Enable Keep alive setting from Web Admin page (TN30084). Also configure keep alive option for OS level as well (TN16328).
