"java.sql.SQLException: IO Error: Connection reset" occurred on our application.
After rebooting JBoss server, our application can be correctly working. But, if we keep the system idle for about 15 minutes, then try to navigate any page that needs DB connection, the issue below will occur. If we log off and login again, this issue will automatically disappear. Could you help us to find the root cause and related fix?
