So I have been having a strange memory issue since upgrading to OS X 10.4.10. Doing nothing, after boot slowly my VM size grows to over 10GBs, and my free memory goes from 1.4GB to 20 MB, with it all going to inactive. And this is not normal VM procedure. After about an hour or two, my computer crawls. Doing anything (moving a window, switching programs, etc) takes 10-20 seconds. I have a 2.0GHz Dual G5, with 2GBs of RAM. My main hard drive has 80GBs free space currently.
Here is a vm_stat followed by another one 2 seconds later:

What is interesting to me is the "Translation faults" section. It just constantly grows and grows, and rather quickly.
Any thoughts? I have scanned my process list, and I don't see anything suspicious running:
