We will need a bit more information before we can help you: - What Java implementation (and version) are you using? What JVM options?
- What servlet container? Tomcat? - Are you using Apache HTTPD in front of Tomcat? - What are the symptoms of "going down"? Do you get any response? From Apache? Tomcat? - Do you get anything in the logs (Apache, Tomcat or GeoServer)? - Do you see heap errors in the logs? - Do you get any mysterious database errors (ORA-something) or hangs? - Is there a firewall between GeoServer and Oracle? from the app-schema manual but relevant to all users: http://docs.geoserver.org/latest/en/user/data/app-schema/data-stores.html#jndi "Firewall timeouts can silently sever idle connections to the database and cause GeoServer to hang. If there is a firewall between GeoServer and the database, a connection pool configured to shut down idle connections before the firewall can drop them will prevent GeoServer from hanging." - Have you tried turning on VERBOSE logging in GeoServer to diagnose the problem? Kind regards, Ben.
