binding_of_caller uses a lot of memory

[apoorvparijat]

I'm using better_errors and binding_of_caller in a Rails app with activeadmin.

It works fine when there is any error in Rails controller. But if the controller belongs to activeadmin part of the code, I can see the memory keeps going up and the page hangs. Memory always seems to go up to 1.5gb and above.

I'm using Rails 4.0.

Problem was with better_errors using up a lot of memory due to arbre gem. Switched to arbre's master branch and that fixed the issue.

Fixed it for me, too.
Working with Rails 4, this is what I have in my Gemfile:
gem 'arbre', github: 'gregbell/arbre' gem 'activeadmin', github: 'gregbell/active_admin'
