    So you request balance after navigating to call logs screen or else, in short what is the co-relation between logs screen & balance requesting webservice.

    Also the number shown after the KERN EXEC text would be important, since it actually tells which problem it is.

    Well i think then you might want to check the flow of app when 2nd request for balance is put till its response is received.Might be you are trying to access the view which is destroyed already when you switched to call logs view.

    well i have tried to check the flow of app. but did't find the proper solution. application still crashed either i am in call log view (after 10 to 20 sec) or navigate to other window (on other window its also take some time almost 10 to 20 sec then crashed) with the error application crashed with KERN EXEC 3

    I have short out one problem when i have select number from call log and switch to other view its not crashed... But now i am still facing one problem when i stay on call log view for 20 to 30 second its crashed. Actually this all problem occur when i have implement balance by using "S60_Platform_HTTP_Client_API_Example_v2_1_en".

    Well as said earlier, its quite possible that you are receiving the response of that balance service after 20-30 secs & as soon as it is received something goes wrong & app gets crashed.You may try putting a wait bar as soon as balance service is requested & delete the same at the instance when response is received, this may help confirming if its due to balance service or else.

    I need one more advice, could you suggest me when we need to call the balance. i have called the balance when my application get registerd and status is true. because when i have move to new view(or call log view) i think DoDeactivate function delete all instances uses in this view.. if you want then i will paste my code here of show balance ..

    Re: Application get crashed with Error KERN EXEC

    Well that depends upon the requirement/flow of your app as when you want to call that service. Try debugging the app by putting break points starting from where the service is called till the response is received(strictly check the flow what happens when the response has been received, put debug points in MHFRunL() function of HTTP class & debug till the last point)

    It may happen that the deleted view is being accessed somehow after the response has been received.
