All 4 ran fine and although my total_bpages for zone2 is 96, the most active_bpages I actually saw was 19 in zone2. (Although I don't know what the difference is between the zones 0,1 & 2 - but the zone0 and 1 figures didn't change). > > Hope that helps, > It does - I'm feeling a lot more comfortable about this 4GB flakey-ness. Thanks! Robert
