Well done for finding it... sounds like one for open.silverstripe.org

Hi Willr

I'm having some massive memory leak problems. When you say large dateobjectsets are we talking about 100, 1000, 100 000 . I'm not sure if the size of my site is causing a problem or the code. We have a lot of many to many relations with fairly large groups in the 100-1000 range and that doesn't seem excessive so I was planning on combing over my code and setting up php debugging software like you suggested but wanted to check with you first whether these are reasonable numbers.

Thanks

Will

ps any more news as to when 3.0 will be available? thanks again

Also remember with memory issues there is no garbage collection by default... I've added this during large dataobject manipulations to reclaim the memory and avoid the dread memory exhausted error...

Just log in to your Database (phpmyadmin etc.) and edit the tables SiteTree and SiteTree_Live. Change the ParentID of the broken pages. For simplicity just change it to 0 (Root) and then move them around in the backend when you're done. You should be able to find the page you're looking for in the DB by looking at the URLSegment (same DB Table).
