FC3 memory usage problem

[Peter Arremann]

I just upgraded my laptop from FC1 to FC3 a few days ago and since then I'm 
seeing terrible memory usages. The laptop has 1GB plus 1GB swap but I've ran 
it out of memory by simply using openoffice, mozilla and a few other smaller 
kde apps. Nothing similar has ever happened to me before and I checked 
everything I can come up with without result. 

Example Mozilla:
Just after starting mozilla I see this:
  $ ps -eo"comm,vsize,rss" | grep mozilla 
  mozilla-bin      97084 29392
After just visiting /. for a few stories the memory usage has grown to
  $ ps -eo"comm,vsize,rss" | grep mozilla
  mozilla-bin      142016 44528


Example OpenOffice: 
Starting OpenOffice 
  $ ps -eo"comm,vsize,rss" | grep soffice
  soffice.bin      143976 51996
Opening a 9 page document with very simple layout (25000 characters)
  $ ps -eo"comm,vsize,rss" | grep soffice
  soffice.bin      157708 68780
After typing the word hert and the rightclicking to get corrections:
  $ ps -eo"comm,vsize,rss" | grep soffice
  soffice.bin      323336 234440


Example Kmail
Starting Kmail:
  $ ps -eo"comm,vsize,rss" | grep kmail
  kmail            44352 24276
After viewing 15 emails from ebay:
  $ ps -eo"comm,vsize,rss" | grep kmail
  kmail            49796 30760
After viewing 100 random emails (about 30% html)
  $ ps -eo"comm,vsize,rss" | grep kmail
  kmail            69144 47132
Viewing the same 100 emails one more time:
  $ ps -eo"comm,vsize,rss" | grep kmail
  kmail            78956 53624


I'm a little suprised to see such memory usage within 15 minutes of booting my 
laptop. If I keep going, I'm running my laptop out of memory within about a 
day. 

Anyone got an idea?

Peter.
