Actually - according to your meminfo output you have something like 700M free at that particular point in time (not 700K) I guess I don't know too much about what the numbers mean coz I can't explain "SwapFree: 1675944 kB" being less than "SwapTotal: 1807272 kB" but "LowFree: 486964 kB" - so you'll have to find a memory guru here or read up on what each actual numbers mean The fact that swap has been used would mean to me that LowFree should be zero - so I'm a bit lost - sorry. <snip> > I just can't see why those 1.3GB RAM should be un-usable.
