Shazron Abdullah commented on CB-2301:
--------------------------------------

Ah I see where the crash might happen now -- when the app is backgrounded/locked, it does a backup of your localStorage, this call is async but I don't think this is where the crash happens. I'm thinking it happens on restore somehow: https://github.com/apache/cordova-ios/blob/2ba2b39339336e274dd8583f260ff0d85e8e48b2/CordovaLib/Classes/CDVLocalStorage.m#L419

At least with your new information we can build a test-case to perhaps repro it: 
1. Set your config.xml BackupWebStorage project setting to the default ('cloud').
2. Read and/or write to localStorage on the resume event (http://docs.phonegap.com/en/2.3.0/cordova_events_events.md.html#resume, see iOS Quirks)

>         Environment: iPhone 5 running iOS 6.0.2 and Phonegap 2.2.0. (Xcode 4.5.2 on Mountain Lion)

> I have implemented a websocket connection (using socket.io) within my app which it uses to communicate with the server. On locking and waking the device, it disconnects and reconnects correctly, but on leaving the device locked for 1 minute or longer when unlocking, the application will crash sometimes instantly, or sometimes after reconnecting with the server.
> If I do the same, but run my app within mobile Safari, it does not crash, leading me to believe this is an issue with Phonegap/Cordova. 
> On app crash, within Xcode I get within WebThread - WebCore::ThreadTImers::sharedTimerFiredInternal() an EXC_BAD_ACCESS (code=1) error
> Screenshot of crash state in Xcode -http://pictat.com/i/2013/1/28/24904screenshot.jpg
> Hopefully someone will have an idea as to what could be causing this, or recommend some tests for me to run etc because I'm really clueless on how to proceed with fixing this!
> Many Thanks,
> Ross
