Sorry for flooding. See attachment. Won't happen again.

This one is the corresponding log for PHP.

I've commited a possible fix that properly closes the database connections after each request handling.

My rationale here is that MySQL connections stacked up until they reached the maximum authorized (around 300 I think), and thus Movim couldn't connect anymore and dropped the session.

I've increased the Session cookie timeout to 1 full day (24 hours). The previous timeout was 1 hour. This seems consistent with the time it took for the problem to happen. More testing needed before closing this bug though.
