4.9.1 Memory Leak
I'm experiencing this memory leak on the current version of Unreal 4.9. I can barely use the editor for 10 min or less before my memory gets so full that I am forced to close Unreal. I can see the memory going up quickly while I have certain blueprints open. As soon as I close them, the memory stops going up but remains where it's at. Open them again and the memory keeps rising until I get the message from windows that I'm all out of memory.
What's weird is that I have been using this version of Unreal for quite a while before this became an issue. This memory leak only happens when I have certain blueprints open. I've worked on these specific blueprints a lot without experiencing this problem before. It's also only happening in a single project so far. I've tried using another project and haven't experienced this memory leak yet.
We're aware of a memory leak when you have enough tabs open that the tab title text is completely culled from view. Does this sound like what you may be seeing?
UE-21203 is the bug tracking that leak.
