Hi, I tried your trick but got:
no more room for vm_map_enter in f5cbbf80
Stopped at eip 0x80109422: ret
call task_terminate($task4)
Kernel page fault trap, eip 0x801474de
Caught page fault (14), code = 0, pc = 801474de
I saw somewhere that you wrote how to list all processes but cannot find
it right now.
