Hi All, We are trying to run our app with latest ruby 1.9.1-p243 and rails v2.3.4 but when we hit some of the controllers mongrel quits with "Trace/BPT trap" error, same thing happens with webrick. There are no additional logs! We have all the latest gems and plugins installed. I would like to debug and see what causing this this but I wasn''t very successful. Can you point me to some tools that I can use? I am toying with Dtrace but haven''t figure it out yet. thanks, --Hakan -- Posted via http://www.ruby-forum.com/.
