usually shows it.
I'm beginning to think the same. I can't nail it down though. I
rebooted 3 days ago. Since then swap partition usage is slowly edging
upward. Immediately after a reboot, and with all the regular services
and applications running and the machine sitting at idle, roughly
1.2Gb of the 2.0Gb of RAM was allocated/used, and swap was at 0 of
4Gb. As I used the machine for my "normal" desktop use... so using
Firefox, Thunderbird, Opera, Seamonkey, Smart, Skype, Ekiga, X-Plane,
etc, the swap partition is up to 670/4095. Slowly... over time it
fills up, and is not being released.
This is only recently... say in the last month or so. I can't nail it
down to what I updated recently that is doing this.
Ideas:
- Undo the updates in reverse order (rpm --last can tell you which).
- Try accounting software (ac): rcacct start. I believe it can help, but
I don't know how. The command 'sa' gives process info.
Then, there most some tool that navigates memory blocks telling who is
the owner of what, but again, I don't know which tool.
In "gnome system monitor", in the view menu I see "memory maps" in grey,
and I don't know how to activate it - but that's just the thing [...] ah,
it shows the map for the highlilght process only. Too bad.
I know i have seen some other tool somewhere... :-?
