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 ... >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. >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 ... :):) >Release-Note: >Audit-Trail: >Unformatted:
