I'm using FMDB in an iOS app. Recently I have received several crash reports from Apteligent about a crash of FMDB:

0   libdispatch.dylib 0x00000001810ab120 _dispatch_main_queue_callback_4CF + 2904

    15  libsystem_pthread.dylib 0x00000001812b9020 start_wqthread + 0

I access to the database from multiple threads. As the documentation says, I have a single instance of FMDatabaseQueue and I share it across all the threads of the app. I'm getting a SEGV_MAPERR crash at the method [FMDatabaseQueue inDatabase:]

This crash happens hardly ever, but I would like to resolve it. Any ideas what is causing it?

Thank you very much.

Like your other question, this crash seems to be a part of your app code and not Crittercism SDK. If you still believe that this has been caused due to Crittercism, you can create a support ticket by sending an email to support@apteligent.com by mentioning the concerned App ID and the direct crash URL. Be noted that the email support is available for paid customers only.

  • I'm not saying that this crash is caused by Crittercism SDK. I wanted to say that I had received in Crittercism several reports about this crash. Sorry for the confusion. – jmartinalonso Oct 03 '16 at 06:43
