    text
    copied!<p>I have an app here that could be boiled down to uiscrollviews with images that you can flick through. I'm experiencing something really strange here though.</p> <p>When flicking through each image (have roughly 60 of them in total), at some point the app just quits. I'm running it in XCode 4 (GM seed 2), and I'm getting no debug info, and no messages in the console at all. Turned on NSZombieEnabled, but that didn't change anything.</p> <p>I'm not even getting a crash log on the device. I've run it through instruments, and it doesn't report any leaks, and my memory usage goes between 700 and 1100KB when run on the device.</p> <p>I even checked each of my "pages" (the ones you flick through) and added messages at init and dealloc, and I can confirm that they're all getting deallocated properly (only keep the current and the pages on each side loaded).</p> <p>Now, this seem to mostly happen at the same point in the app when I just start at the beginning and flick through each page going right, plus or minus a few pages, all pointing toward a memory issue, I do get a memory warning from the device, but there is absolutely nothing pointing to me using a lot of memory at all, nor that there are any leaks.</p> <p>I got this from the console on the device when the app quits:</p> <blockquote> <p>Mar 8 14:13:37 unknown configd[26] : jetsam: kernel memory event (92), free: 451, active: 2894, inactive: 2267, purgeable: 0, wired: 16709</p> <p>Mar 8 14:13:37 unknown configd[26] : jetsam: kernel termination snapshot being created</p> <p>Mar 8 14:13:37 unknown com.apple.launchd[1] : (com.apple.AOSNotification) Exited: Killed: 9</p> <p>Mar 8 14:13:37 unknown com.apple.launchd[1] : (UIKitApplication:com.apple.mobilemail[0xc2ee]) Exited: Killed: 9</p> <p>Mar 8 14:13:37 unknown com.apple.launchd[1] : (UIKitApplication:no.NRC.NRCMag[0x3c6c]) Exited: Killed: 9</p> <p>Mar 8 14:13:37 unknown com.apple.launchd[1] : (com.apple.dataaccess.dataaccessd) Exited: Killed: 9</p> <p>Mar 8 14:13:37 unknown SpringBoard[30] : Received memory warning.

And why am I getting memory warnings when Instruments (and a thorough look at my code) says that I'm not using much memory, nor leaking?</p> <p>Help!</p> <p>EDIT: Got 3.2.6 up and running here and the console now gives me this:</p> <blockquote> <p>Program received signal: “0”.</p> <p>Data Formatters temporarily unavailable, will re-try after a 'continue'. (Unknown error loading shared library "/Developer/usr/lib/libXcodeDebuggerSupport.dylib")</p> </blockquote>
