The tail of two systems and one hard drive. I install centos 5 on a HD while it is in a Compaq with 256Mb memory. After install, i am in graphics mode (Gnome) and top reports not quite all 256Mb used. Then I move the HD to a decTOP with 512Mb memory. I am running non-graphics (init 3). I ssh into the unit and top reports not quite all of that used..... So what ate up more than 256Mb

...ping 5 seconds memory freed So what asterisk says is about right. When I look at the info from 'cat /proc/meminfo', I see this: cat /proc/meminfo MemTotal: 16361780 kB MemFree: 151844 kB MemAvailable: 14883060 kB Buffers: 5468 kB Cached: 14773136 kB SwapCached: 224 kB Active: 2019568 kB Inactive: 13592124 kB [...] which would mean that I have 14GB buffered/cached, and 'free -h' confirms this. Apparently, the cache remains persistently occupied. Since I'm currently performing backups, it's not surprising that t...

Hi everyone, Here are new releases of bio-cgroup. Changes from the previous version are as follows: - Accurate dirty-page tracking Support migrating pages between bio-cgroups with minimum overhead, but I think such a situation is quite rare. - Fix a bug of swapcache page handling Sometimes, "bad page state" is occurred since the memory controller has temporarily changed the swapcache page handling. The following is the list of patches: [PATCH 0/5] bio-cgroup: Introduction [PATCH 1/5] bio-cgroup: Split the cgroup memory subsystem into two pa...
