I'm trying to track down the cause of my site to locking up using NewRelic to examine the slowest transaction (the site is running Radiant CMS, and the slow transaction in this case is SiteController#show_page). In one of the transactions wherein the site becomes unresponsive, there are two calls to "(unknown)" that take approximately 77 seconds. Has anyone run into something like this before?
