I have a app, when I had run it for a few minutes, it always crashed. I check the crash log, it always said malloc: * mmap(size=1048576) failed (error code=12) * error: can't allocate region securely I checked the memory leaks by using the instruments tools, but did not find any memory leak. I wonder if there are some memory leaks the instruments can not find, or some other reasons for the crash. any help will be appreciated!
Edit:
I used the time profiler to check the performance. but I don't know what's the key point because the top items are these:
Running Time Self Symbol Name 6494.0ms 9.4% 6494.0 -[DLStarView initWithDefault:highlighted:position:allowFractions:] (my app has a lot of list, each item has a self made star view)
Running Time Self Symbol Name 5848.0ms 8.4% 5848.0 +[ASIHTTPRequest runRequests] (my app always get data from sever)
Running Time Self Symbol Name 2169.0ms 3.1% 2169.0 -[BMKUserLocationInternal updateLocationInfo]
Running Time Self Symbol Name 1435.0ms 2.0% 1435.0 -[EGOCache imageForKey:]
Running Time Self Symbol Name 1252.0ms 1.8% 1252.0 -[KLRestDetailViewController tableView:cellForRowAtIndexPath:]
is it userful? how can I check if I stuffing a bunch of stuff?
PS: this crash only appear on the real device, I ran it in the simulator for about 20 minutes and the app still run smoothly, my device is iPhone4S iOS 6.0.1
I set a break point and got the messages:
the crash thread messages are not always the same but in the console output, It always said malloc: * mmap(size=1048576) failed (error code=12) error: can't allocate region securely ** set a breakpoint in malloc_error_break to debug
I was so confused by this bug for a few days, any idea? thanks!
