Hm. I did a
cat /proc/`pidof thebigbinary`/smaps | grep Dirty
and got only about 3 MByte of dirty data. So it looks like this is not the (whole) problem (just a part). The Rss part of the /proc/pid/smaps report counts to about 14 MBytes. What is this saying exactly? I thought, those are the pages which aren't stealed by the VM from the app. Am I right?
