If -list displays 10 entries, then yes, there are 10 sessions. By 'session', I here mean a 'server process'. When you attach to a session, a 'display' (or 'client') is created. A single session can have several (or none) displays. However, 'screen -list' displays only the 'sessions', not 'displays', so if you attach to 5 sessions, however many times, it should only display 5 entries. It almost sounds like instead of attaching to an existing session, new sessions are created. Can you confirm that the attaches are indeed being successful?
