4 days later:
Node 0, zone DMA32
nr_inactive_file 404276
nr_vmscan_write 2897
avg_age_inactive_file: 318208
Node 0, zone Normal
nr_inactive_file 4677
nr_vmscan_write 92536
avg_age_inactive_file: 3692
Inactive pages in the Normal zone are reclaimed in less than 4 seconds
(vs 5 minutes in the DMA32 zone), nr_vmscan_write is high and constantly
rising.
