I typically run Thunderbird, Firefox, a terminal or two, Gthumb, Gimp, Qcad, Gedit, Libreoffice, Inkscape, Document Viewer and occasionally Virtualbox.

It seems to me that there are quite a few extra copies of some processes populating memory after running a session for a few days. Namely, dbus-daemon, gvfsd and gconfd-2. The more I use the session, the more of these processes appear. After a while they start using up a significant amount of memory and system response seems to slow down.

Logging out and back in did not alleviate the problem. Rebooting did. But, I will have to reboot again in a week or two to free up the memory used by these leftover processes.

The example session used to get the following results was probably well over a week in use.

Before rebooting:
$ ps -ef >prereboot.txt
$ grep -i dbus-daemon <prereboot.txt|wc -l
40
$ grep -i gvfsd <prereboot.txt|wc -l
78
$ grep -i gconfd-2 <prereboot.txt|wc -l
37

After rebooting:
$ ps -ef >postreboot.txt
$ grep -i dbus-daemon <postreboot.txt|wc -l
4
$ grep -i gvfsd <postreboot.txt|wc -l
5
$ grep -i gconfd-2 <postreboot.txt|wc -l
