This is because you open one connection per session and the number of sessions incease. :) It would be better if you use ConnectionPooling instead of managing your own session.
Otherwise, do the following:-
1. Reduce your session timeout
2. Make sure no connection remains open
3. It would be better if you make a single connection in your application and manage it somehow
It seems like your sessions are never killed, or at the end of session, you never close your existing session.

One connection only? Then why did you increased the number of connections
to 800? Sorry, I might be missing some point here.
