I would like to know that, too. I have exactly the same problem ;)

Although I keep roughly the same (admittedly large) working set of running 
programs around by the time more and more memory seems to get used. Closing 
and reopening single heavy programs which e.g. might collect a lot of undo 
information like KDevelop doesn't help.

But restarting the restored session helps. Every four, five days I have to do 
this to get rid of too much swapping.

What could be done to find the leak? I guessed from the above it is X, perhaps 
keeping more and more pixmaps around noone uses anymore, but 
xrestop :
Pixmaps:  348724K total, Other:   20321K total, All:  369045K total
top:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 3106 root      15   0  672m 484m 1872 S  1.3 47.8  77:46.07 X
suggest X uses much, but not 2 GB.

Does anyone have a script prepared to track which processes steal the memory 
over time? Or any other phenomenon which could be the culprit?
