How stable is your Confluence system and what's your technology stack? I've always used ubuntu + mysql + apache mod_proxy and it's been rock solid on Confluence version 3.2 (weeks and weeks (and likely weeks) before an unexpected down).
Currently at a new gig with a new version and a setup that I didn't control, and it's going up and down like a slinky. Can't make it through a week (and sometimes a day) without either losing our ability to connect to it or having it crash. Still trying to locate the problem (is it confluence, our machine config, network gremlins, etc...) and work with IT to resolve it.
So, I'm just curious. Once you get through your initial install and shakedown, how would you characterize the stability of your system? What's your technology stack?
