Linux emulation freezes machine after heavy usage of cpu and memory

After random time, since begin cross-compiling within linux emulation
environment. Machine totally freeze. I not see any kind of useful clues
like memory dumps or entering into internal kernel debug DDB* ...

(* remark:: I configured dump device and ddb kernel support ;-))

P.S. Products of Wind River with which I work has not native support for
FreeBSD.  This problem is important for me! I worked from many time like
that and after upgrade from FreeBSD-8 to FreeBSD-9 I faced with this
strange problem ...

Fix: 

Fast workaround:

Install virtualbox or qemu. Install inside it some linux distribution.
Export your home directory through NFS and mount from linux distro home dir ;)
And all your further linux related tasks you should execute into linux guest :>

That is fast and ugly workaround solution ... :):)
How-To-Repeat: Compile into linux emulation some big source tree or I guess to see similar
result when you get all physical memory and cpu time.
