And what makes you think that: a) Numbers given in SIZE/OFF column on your system for a particular type of object is memory used? Note that e.g. window size is not a memory, as well as socket buffer size. b) The particular column you are counting _is_ SIZE/OFF? > > > 2013/3/29 Maxim Dounin <[email protected]> > > > Hello! > > > > On Fri, Mar 29, 2013 at 06:04:54PM +0800, MCoder wrote: > > > > > my nginx is just a http tunul proxy http connection, and max connection > > is > > > just lower than 100. > > > > > > # ps aux > > > root 19849 0.0 0.0 18028 2452 ?
