Unity Not Responding after leaving it at idle for a few hours



Unity Not Responding after leaving it at idle for a few hours.

Unity becomes unresponsive (hangs) when left alone for a few hours.

This happens on the OSX as well as Windows. This occurs when Unity is left at idel (not in play mode) for a few hours.

I have narrowed this down to potential use of the profiler where if I don't use the profiler and leave Unity for a few hours it is fine. But if the profiler was used, then a few hours later Unity will be frozen and require killing the task or force quit on OSX.

It doesn't matter what project is loaded or scene.

    Yes, this is still happening all the time. Even on latest version 5.3.4 P6.

    I've just installed Unity for the first time and this still happens for me. Installed 5.1, 5.2 and today 5.3.0f4, all win7 64-bit, and all hang after about 10 minutes on an empty project.
