Dear list, I have a core-data app which syncs its data over mobile-me via sync services. Every couple of days or so, the app crashes on different machines. The stack trace is pasted below. I'm using essentially the same syncing code I use for other apps and I haven't seen this problem before.
Can anyone provide any hints from the stack trace? Many thanks, Martin Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000000 Crashed Thread: 3 Application Specific Information: objc_msgSend() selector name: handleMocChanges: Thread 0: Dispatch queue: com.apple.main-thread 0 libSystem.B.dylib 0x00007fff81e152fa mach_msg_trap + 10 1 libSystem.B.dylib 0x00007fff81e1596d mach_msg + 59 2 com.apple.CoreFoundation 0x00007fff87fdb3c2 __CFRunLoopRun + 1698 3 com.apple.CoreFoundation 0x00007fff87fda84f CFRunLoopRunSpecific + 575 4 com.apple.HIToolbox 0x00007fff83c6c91a RunCurrentEventLoopInMode + 333 5 com.apple.HIToolbox 0x00007fff83c6c71f ReceiveNextEventCommon + 310 6 com.apple.HIToolbox 0x00007fff83c6c5d8 BlockUntilNextEventMatchingListInMode + 59 7 com.apple.AppKit 0x00007fff86b7f29e _DPSNextEvent + 708 8 com.apple.AppKit 0x00007fff86b7ebed -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] + 155 9 com.apple.AppKit 0x00007fff86b448d3 -[NSApplication run] + 395 10 com.apple.AppKit 0x00007fff86b3d5f8 NSApplicationMain + 364 11 com.bobsoft.Trips 0x00000001000014dd main + 33 (main.m:14) 12 com.bobsoft.Trips 0x00000001000014b4 start + 52 Thread 1: Dispatch queue: com.apple.libdispatch-manager 0 libSystem.B.dylib 0x00007fff81e2e08a kevent + 10 1 libSystem.B.dylib 0x00007fff81e2ff5d _dispatch_mgr_invoke + 154 2 libSystem.B.dylib 0x00007fff81e2fc34 _dispatch_queue_invoke + 185 3 libSystem.B.dylib 0x00007fff81e2f75e _dispatch_worker_thread2 + 252 4 libSystem.B.dylib 0x00007fff81e2f088 _pthread_wqthread + 353 5 libSystem.B.dylib 0x00007fff81e2ef25 start_wqthread + 13 Thread 2: 0 libSystem.B.dylib 0x00007fff81e2eeaa __workq_kernreturn + 10 1 libSystem.B.dylib 0x00007fff81e2f2bc _pthread_wqthread + 917 2 libSystem.B.dylib 0x00007fff81e2ef25 start_wqthread + 13 Thread 3 Crashed: 0 libobjc.A.dylib 0x00007fff87ec7120 objc_msgSend + 44 1 com.apple.Foundation 0x00007fff806c484e _nsnote_callback + 167 2 com.apple.CoreFoundation 0x00007fff87fe7a90 __CFXNotificationPost + 1008 3 com.apple.CoreFoundation 0x00007fff87fd4008 _CFXNotificationPostNotification + 200 4 com.apple.Foundation 0x00007fff806bb7b8 -[NSNotificationCenter postNotificationName:object:userInfo:] + 101 5 com.apple.CoreData 0x00007fff887a8843 -[NSManagedObjectContext(_NSInternalNotificationHandling) _postObjectsDidChangeNotificationWithUserInfo:] + 99 6 com.apple.CoreData 0x00007fff887df985 -[NSManagedObjectContext(_NSInternalChangeProcessing) _createAndPostChangeNotification:withDeletions:withUpdates:withRefreshes:] + 325 7 com.apple.CoreData 0x00007fff8878d3db -[NSManagedObjectContext(_NSInternalChangeProcessing) _postRefreshedObjectsNotificationAndClearList] + 107 8 com.apple.CoreData 0x00007fff8878c506 -[NSManagedObjectContext(_NSInternalChangeProcessing) _processRecentChanges:] + 86 9 com.apple.CoreData 0x00007fff8878b98b -[NSManagedObjectContext executeFetchRequest:error:] + 155 10 com.apple.syncservices 0x00007fff84b6865d -[ISDPersistentStoreSyncer _pushAllRecordForSyncEntityName:] + 258 11 com.apple.syncservices 0x00007fff84b68acd -[ISDPersistentStoreSyncer _pushChanges] + 422 12 com.apple.syncservices 0x00007fff84b662b9 -[ISDPersistentStoreSyncer synchronize] + 77 13 com.apple.syncservices 0x00007fff84b65986 -[ISDPersistentStoreSyncer synchronizerThreadMain] + 83 14 com.apple.Foundation 0x00007fff806c4e8d __NSThread__main__ + 1429 15 libSystem.B.dylib 0x00007fff81e4e456 _pthread_start + 331 16 libSystem.B.dylib 0x00007fff81e4e309 thread_start + 13 Thread 3 crashed with X86 Thread State (64-bit): rax: 0x0000000000000000 rbx: 0x0000000100487d60 rcx: 0x0000000102f24910 rdx: 0x0000000102f24970 rdi: 0x0000000100487d60 rsi: 0x000000010004bd5c rbp: 0x00000001149fb2f0 rsp: 0x00000001149fb298 r8: 0x0000000000000000 r9: 0x0000000102f24970 r10: 0x000000010109b9b0 r11: 0x00000001004e787b r12: 0x00000001004a7d70 r13: 0x0000000102f24970 r14: 0x0000000102f24910 r15: 0x00000001003f18b0 rip: 0x00007fff87ec7120 rfl: 0x0000000000010206 cr2: 0x0000000000000000 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Martin Hewitson Albert-Einstein-Institut Max-Planck-Institut fuer Gravitationsphysik und Universitaet Hannover Callinstr. 38, 30167 Hannover, Germany Tel: +49-511-762-17121, Fax: +49-511-762-5861 E-Mail: martin.hewit...@aei.mpg.de WWW: http://www.aei.mpg.de/~hewitson ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
