Dear Seatha Raman,

Starting from October 1st, Kaa crew stopped supporting google forum and shifted totally to http://stackoverflow.com/questions/tagged/kaa, see - https://groups.google.com/forum/#!topic/kaaproject/tBsBmSGGDBg

And please provide more information about your problem such as step to reproduce, which demo app you run or create a custom one,  did application recover after this exception and start working correctly?
