I installed v2.2.0 and now my site crashes all the time
Most likely your theme template(s) (don't forget the subthemes) was using some deprecated 1.0 style function calls. All the 1.0 style code was removed from v2.2.0 and the failure to update the custom theme to remove all the obsolete functions (they were deprecated when v2.0.0 was released) has now been exposed. This article explains how to update your custom theme template(s).
