END QUOTE is that the the kernel is somewhat more likely to deadlock or panic because it may need to allocate memory in order to swap out some memory. The purpose of swapping out that memory?: Likely to free RAM for other uses. So it can need to allocate memory first in order to free memory. This may not be possible, depending on conditions at the time. The indication was that such deadlocks/panics are very rare, even if the system produced the warning lines. =3D=3D=3D Mark Millard marklmi at yahoo.com
