I am getting memory error on development machine (sometime on deployment m/c also) on opening a screen. The screen has a tree view and one browser. The total number of records are 12100 now (It will go upto 50000).
The app.log of development m/c is -

How to solve this issue?
Will app has limitation of number of records?
Is it due to ‘forget paasword’ add-on? (as i have added this add-on recently) or due to more data?
regards
