receive memory warning but consumer fewer

Question

I'm doing a app like photo browser just like the "Photo" on iTOuch. And I use a third-party lib : https://github.com/kirbyt/KTPhotoBrowser When I scroll the photos several times, the app crashes. The log shows that it has receive memory warning.

Then I use instrument to check the memory (I choose Memory-Allocation).

I track the Live Bytes and Overall Bytes for "All Allocations". However, the Live Bytes is never more than 5 MB, and the Overall Bytes is beyond 100 MB .

When the app carshes, the Live Bytes is 3.97MB and the Overall is 125.48MB.

I think Live Bytes is the memory currently used, and it seems it costs a little.

Why the app still crashes? Xcode 4.2 4D199,Lion 10.7.2(11c74), iTouch ios5.0.1 beta2. Below is the screenshot, and the instrument configuration is the default. enter image description here

Any idea?

the crash log is like:

you should provide all the relevant line for the crash but not the complete dump. — UPT
@UPT, I don't know where causes crash and hence where is the relevant line. — scorpiozj

It is my own fault! when I use NSURLConnection to detect the MIME-TYPE of the file, the memory of the connection is never released and it becomes larger and larger(As I detect the type of more than 100 files).

I reconstruct the code.
