High virtual memory usage

I am only running Safari and Activity monitor as front end applications, however the virtual memory usage is clocking up to more than 50GB.

The laptop (Macbook Pro) has 3 GB of Ram and reports approx. 2 GB of free memory. Everything is sluggish and slow (takes 10 minutes to start Aperture).

When looking in Activity monitor Safari uses 87 MB of memory and 1GB of virtual memory.

Is there anything I can do to improve the situation?

Macbook Pro (Intel), Mac OS X (10.5)

Couple of suggestions:

(1) Quit and relaunch Safari. See if that brings the memory usage down.

(2) Try quitting and relaunching the Dock. Open the Terminal application and enter *killall Dock* That should kill and then automatically relaunch the Dock.

Post back here if either helps. If they do, please also mark this posting as having "Solved" your question. Thanks

I tried closing some applications and relaunching.

My M-Audio Firewire mixer (an incredibly simple application) uses 696 MB virtual memory. After closing and relaunching it went straight back to 696. Adium was over 700 MB and returned after a relaunch as well. I noticed there isn't a single application using under 500 MB.

Surely there is something different about how virtual memory is counted in this os. Moving that much information would take a long time and slow down the computer a lot. Of course, this could explain a lot, if you know what I mean.

Since upgrading to 10.5(.1) my Dual G2 2.0 has been chugging and the HD accessing forever. The finder has been crashing and I'm hearing the HD crunching data. The thing is ssslllooowww.

So I looked at my memory usage and I've got you beat. All of my open apps are using 700+ MEGS of VM each. That's like 30+ apps, including my mouse driver!

Firefox is using 965 megs of VM. My dock is using 750 MEGS. It isn't really possible since I only have 10 gigs of space left.
