> app freezes if device is offline
> --------------------------------
>
> Key: CB-10712
> URL: https://issues.apache.org/jira/browse/CB-10712
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS
> Affects Versions: 4.1.0
> Environment: iOS
> Reporter: simon tretter
>
> similar to CB-10530, but this one happens every time when I start the app
> when my device is completely offline (no wifi, no sim inserted). not sure how
> or if this is offline thing is really related, but at least it's easy to
> reproduce due to the reason that i happens all the time.
> I have ajax request in the app, but seems not related. I can reproduce the
> issue even if I skip all the network stuff. The app freezes during start.
> always on a different line of code.
> last log lines show a memory warning
