xwiki production ready?

All, I have a few questions concerning the readiness of xwiki for production: - how 'production-ready' is xwiki in the actual version? - are there any known issues which can affect the production (load, leaks, ...)? - there are links which generates a stack trace (e.g. http://www.xwiki.org/xwiki/bin/view/Mai ) . Is there a way to define a general error page so that any stack trace is caught by this page (and can be hidden)? Thanks Yves
