its probaly exactly what you say, most firewalls, NAT routers, etc will time
out idle sockets after a certain number of minutes... They have to do this,
otherwise the firewall's connection tracking tables will fill up with old flug.
only good solution is to catch the exception, and attempt to reopen the
database connection, and retry the operation....
