Description of problem: After several issues where the UI has locked up I found this in the error log which seems to be about the same time of the UI lockup.

Do we have more information about recreating this Jared? Can it be closed if not? I'm not quite sure how this could occur.
Just in case anyone sees this again, I got around it by checking to make sure that the attribute being written hasn't already been destroyed. (the attribute setter in /Users/duhlmann/.rvm/gems/ruby-2.3.4/gems/activerecord-5.0.7/lib/active_record/attribute_methods/write.rb). Seems to only be a ruby 2.3 issue.

Hi Jan, Please see the other comment and please followup here: https://bugzilla.redhat.com/show_bug.cgi?id=1781202#c4 For now, please increase your web service worker count and memory threshold. We'll continue to look at the cause of the side effect error "can't modify frozen hash". We should also figure out why the memory growth is now happening or if something recently changed to cause this.
