  1. POMy iphone application crashes
    text
    copied!<p>I made an application that should run constant until I stop it. What it basically does is getting some data from connected another device and send that data to the server periodically using NSURLConnection, and read data from the server periodically and visualize that data as a graph using NSXMLParser.</p> <p>I ran the instrument to check allocs and leaks. No leak at all. memory monitor shows consistent 5.2MB. Objectalloc graph is stable, Net bytes of objectallo is arouend 480000 and #net is around 6400.</p> <p>The problem is the application is stopped (or crashes) about 12 hours later. What are possible problems? I have absolutely no idea where to start finding the problem because neither a debugger nor the instrument don't show any error or problem.</p> <p>[added]</p> <p>1 . as Paul's suggestion, I ran my app on the simulator and got some error messages after 5 hours of running.</p> <pre><code>InAir(64628,0xa050c720) malloc: *** error for object 0xc015bc87: Non-aligned pointer being freed *** set a breakpoint in malloc_error_break to debug InAir(64628,0xa050c720) malloc: *** error for object 0xa0200100: pointer being freed was not allocated InAir(64628,0xa050c720) malloc: *** error for object 0x2080a043: pointer being freed was not allocated InAir(64628,0xa050c720) malloc: *** error for object 0x120100: pointer being freed was not allocated InAir(64628,0xa050c720) malloc: *** error for object 0x34a00000: pointer being freed was not allocated InAir(64628,0xa050c720) malloc: *** error for object 0xc1d3a1b1: pointer being freed was not allocated InAir(64628,0xa050c720) malloc: *** error for object 0x46b0a1b1: pointer being freed was not allocated InAir(64628,0xa050c720) malloc: *** error for object 0xc1d3a1b1: pointer being freed was not allocated Program received signal: “EXC_BAD_ACCESS”. </code></pre> <p>2 . About NilObject's comment... I didn't know the organizer has crashlog. Yes it has.</p> <pre><code>Incident Identifier: 0ADC2722-BF4B-457F-A224-4A946810FB1F CrashReporter Key: f62c1dc12071b63c1e21d612962ee6aad74b4503 Process: InAir [3154] Path: /var/mobile/Applications/9471A5CA-97E1-4E52-A934-9CE33DC5A5DB/InAir.app/InAir Identifier: InAir Version: ???
