gc: too many threads, crash using Unity 4.2

Question

When I work in the editor of the new Unity 4.2, the editor crashes pretty quickly with the error gc: too many threads. I can't find a specific action that causes this nor do I know what is actually the cause of this. I've never had any problems before (actually, in 3.5 Unity would crash frequently due to memory leaks, but not nearly as often as this). My system should be powerful enough and I don't notice Unity taking up an extreme amount of memory when this happens.

I have already tried removing and reinstalling Unity, but it did not help. Working on a different project also did not help.

I searched around a bit, but it does not seem like are many people suffering from this same problem.

Any suggestions?

The problem goes away if you are running Unity on the integrated graphics card instead of the dedicated GPU - but of course you may want that additional graphics power!

Having same problem. Empty project crashing as soon as you try and do anything when running two monitors. Works fine of either monitor as long as its the only one enabled.

Running GeForce 650M

In my case, I use Quadro 2000M as GC and double-screened with a cintiq screen. Even I run Unity on the primary screen which I set it to the laptop screen. The error happens continuously when I found that in "Set PhysX Configuration" in NVidia Control Panel, the quadro seems is in charge of the attended screen while the integrated graphics card is in charge of the laptop screen. So after I set the attend screen the primary one and run unity on that, the error never happened again!
