Hello, I am using unity 2.5 on OSX 10.5.5 on a Mac Pro. I working on an environment which seems to be crashing my whole system in the sense that I can still use the mouse but I can’t force quit or exit unity when the game freezes. I have less than 200 draw calls but a good number of textures. The frame rate however doesn’t seem to be getting slower when it crashed. Actually freezing is a better word.
If anyone has any ideas what aspect of unity could be causing this maybe I can start trouble shooting.
Thanks for any help
Can you be more descriptive in your definition of the problem? What leads up to the crash? Does it happen in every project or scene, or just one? Are you previewing the game in the Game view or just editing? If the game is playing and and the Editor suddenly freezes, it’s likely that there’s an infinite loop somewhere in one of your scripts, but without more details it’s hard to say for certain.
It only happens in one scene. It happens in the editor and if I compile an executable. It happens at random times in the same scene file so I can’t predict hen it will freeze. It seems to happen every time I walk through the scene for a few minutes but at different places. The movement will just stop and I will have my mouse still working and my keyboard can still control the volume on the computer but other than that I can’t do anything(Hide unity, quit or use spaces).
This sounds like you may have a memory leak somewhere in your code… are you using the “new” operator anywhere in your code?
or maybe you can download 2.5.1 first and see if that fixes it

I tried unity 2.5.1 and it still crashed. Also I am not using the new operator in any scripts. It’s just the FPS moving through an environment.
How high is the polygon count of the environment? Are you using mesh colliders on a really high poly mesh?
No really hight poly counts and I’m using box colliders whenever I can.
what do the stats mention about texture memory usage? Are you potentially requesting more than your graphic card offers
I managed to get a screen shot when it crashed. Here are the stats.
all no problem.
either you have a plugin that takes it to hell or its a system issue I would say.
Overheating, general start of failure, driver issue, …
