I've read from Jeff that the actual limit is 480M (some space must be saved for vmalloc(), i.e. kernel pageable memory). > It stopped complaining at about mem=200M (roughly IIRC) Well, that's too low, so yes, there's some problem. Especially because memory is shrunk down to 28M... Which is the host distro? Having a RH/Fc could be a cause (I don't know the current situation with these). > > > # uname -a > > > > Does the box locks up thereafter?

But I assume it locks up. Was SMP enabled?
