Hi,

'LOGOFF BY CLEANUP'  occurs when a session hasn't explicitly closed the
connection & Oracle has to clean the session up itself.

Sounds like your new server is behind a firewall that drops connections
after 2 hours, causing the above. Talk to your network admins and ask what
network hardware is between the app and database server.

Thanks,

Phil
