Not i don't sure about this:-)) I don't have very good knowns about Linux
VM managment. And for me looks very stange that swap grows, but not any
swap activity (i monitor it throw follow vmstat -s | grep 'pages swapped
out' | awk '{ print $1 }' and vmstat -s | grep 'pages swapped in' | awk '{
print $1 }'). So looks like that you right, and i has filled up my
knowledge:-))2012/4/15 Віталій Тимчишин <tiv...@gmail.com> > BTW: Are you sure system doing wrong?
