OutOfMemoryException i want Disable category tree in bo

[sney1984]

Hello,

Is there a solution to avoid the OutOfMemoryException error? Otherwise I have to disable the category tree in BO because I have about 20,000 vehicle categories, the loading time is more too long, 10 times out of 9 I get error 500, and when it works it doesn't never completes the loading of the page as seen in the attached photo.
If I enable debugging to find what to change I always get error 500. If there is no solution, what and where to change to disable it?

Thanks
