Can you talk more about what the glitches were like? We're a few months away from production with our first product that uses redis, so this is very interesting.
Have you simulated a network partition? How does redis handle the reconnect?

However we also use ssh tunnels for our continuous integration (jenkins) and the irc bots that we use for development (http://3scale.github.com/2012/06/29/irc-driven-development-p...).
In this setup we have the autossh going awol every one or two weeks. But as the blog post mentions, the ssh tunnel runs between our HQ (fiber) and Amazon, not very reliable. Furthermore, there is a lot of idle periods, which seems to trigger most of the issues. We cannot give more specifics since we forcefully just restart the daemon with a monit/munin combo.
The outbound firewall of our company drops my outbound ssh connections if they are idle for just 5 minutes. Adding:-
Host *
ServerAliveInterval 60
A corresponding ClientAliveInterval setting in the sshd_config file also helps mask the problem [EDIT] if I ssh home from a machine at work that doesn't share my home directory ssh config file.
