Ronald Jeremy commented on CB-2301:
-----------------------------------

This issue should NOT be closed.  I have been tearing my hair out because of this.  In my apps the websocket needs to stay connected even when the app is in the Inactive and background states, so closing the socket on "pause" is not an option.

I am using the socket.io 0.9.9 client, Cordova 3.4.0, and iOS 7.1.  Everything works great when the app is in active, inactive, and background states.  But when the app goes into and comes out of suspended state (i.e. a few minutes after locking the screen), it crashes almost every time with EXC_BAD_ACCESS.  If i don't have a socket open when the app goes into suspension = no crash.  And also it works fine on just a regular mobile safari page.  So this bug definitely does exist.

If there was an event like "app will be suspended" that would be a possible workaround to close the socket then, but I don't believe such an event exists.

> 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
