Created attachment 142291 [details] Thread dump of my locked up nb made with jvisualvm... The IDE locks up after a few minutes of usage. So far i see no connection between the freezes and the component used at the time. It have locked up in the editor, resolve conflict window, settings, plugins and UI editor. I tried out build 201311170002 and it is still hanging. The operating system is OSX Mavericks. java -version: java version "1.7.0_40" Java(TM) SE Runtime Environment (build 1.7.0_40-b43) Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode) Attached a thread dump made with visual vm. Since I can reproduce this any time, feel free to ask for logs or whatever you need from the IDE. Just tell me where it is. I also have a thread dump if you need it.
