Could you please also try to copy something in the VM > around? Would be interesting if that causes the crash. hail, I have some more info on this. In my work pc there is latest vbox from svn installed. when I tried to run FAH in its smp version, I got a frozen pc. I'm now trying the same test at home, always 7.2-STABLE, and for more than two hours it is fine, at full load. I think it is exactly what you said above. in my work pc, I used 384 ou 512MB Ram for the vm, here I used 768M. so the pc has free memory. debian here says has 284000KB of free memory and 485000KB of used ram. when I tried the single core client, which uses far less ram, it was ok. so I think the swap is being used and that relies on the disk. this I said makes sense to you all ? if so, great cause I can put more ram to the vm and run my fah client. the machine uses both cores of this E6750, and the performance is the same as native linux. thanks all ! matheus -- We will call you cygnus, The God of balance you shall be A: Because it messes up the order in which people normally read text.
