My MacBook Pro has 8G RAM. Recently memory leak offen happened. Page outs and swap used kept increasing. The last time it used ~8G swap space.

But in Activity Monitor, I can't find any process has a large value in 'Real Mem', 'Private Mem' nor 'Shared Mem' column.

I checked the %MEM column in output of 'ps -ev', all processes occupied less than 1% of memory. The full output is put in this gist:

What the way to diagnose OSX memory leak issue?

The %mem statistic seems to be ... weird. I can't figure out what it's a percentage of. Try ps -axv instead, and take a look at the RSS (resident memory in KB) and VSZ (virtual memory, also KB) columns. – Gordon Davisson Feb 12 '13 at 7:13
Memory leak might be caused by Since I removed this app, free memory > 3G for a few days. But this question is still valid, because seeing the output from both Activity Monitor and ps -axv, used not too much memory. – aleung Feb 18 '13 at 9:19
I am in a similar situation, and would also like to know the answer. Perhaps we should look in the console and system logs. – user55316 Aug 18 '13 at 14:09
