Memory leak?

[CapnJackGig]

Loaded Lion on 2010 Macbook Air yesterday. Prior to the install, I had 50 gig of free space left. After the install I had 51.04 gig. Noticed last night before I went to bed that it said I had 46 gig of free space. All I had open during the day were Safari, Chrome, iTunes, and Mail. This afternoon I restarted the Air and I'm once again at 51.04 gig of HD space. Any idea what would cause 5 gig of the HD to get eaten up in a day's time?

That's not a memory leak. Memory is RAM not storage space.

Secondly, do you have Time Machine enabled? It does have "Local BackUps" which could eat up drive space.

Or are you paging out, the swap space could use up ram also.

It's virtual memory. When RAM fills up, the system uses your hard drive as virtual RAM. When you restart the machine, the virtual RAM is emptied and you get your hard drive space back.
