I have a strange memory issue: I've been running out of free memory for months now, which I thought was OK, since I use the Creative Suite apps and Xcode regularly, all of them is quite memory intensive.
But somehow the situation seems to be getting worse. Today I logged off to free up some RAM, then when logged back in, all the 4 GB of my RAM was used. (I've uploaded the list to here)
I exported the processes, and added the memory usage, but they add up to 684 MB only.
("All Processes" is selected in Activity Monitor)
How could I check which process is using up the memory in the system?
