Redmine

it occurs when I try to view a project or a project's issues. both times fails in the #rolled_up_trackers method in the project model. I can't figure out how to get any additional info from it since the "stack is too deep".. guess I never had this error in any other rails project I've dealt with.. at any rate.. I was running ruby 2.0 so I upgraded to ruby 2.2 but the error persisted.. any suggestions would be greatly appreciated.. I left the plugins that existed in my previous Redmine 2.3.. I guess I can start removing them if folks think it's a plugin causing this..

here's the current "stack trace"
SystemStackError (stack level too deep):
app/models/project.rb:428:in `rolled_up_trackers'
app/controllers/projects_controller.rb:140:in `show'
