simon tretter created CB-10712:
----------------------------------
Summary: 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. now sure how this is related. I have some network access in the app, but seems not related. the app freezes during start. always on a different line of code.
last log lines show a memory warning

and after a while the app sends a EXC_BAD_ACCESS in a WebThread.

As a side note, I also experience this sometimes when I'm not offline. Couldn't figure out if this is now fixed by 4.1. But I guess not.
