Asp.net mvc sencha application is not working on Safari Ipad

I have implemented an applciation asp.net mvc +sencha. The application is working fine when i have test it on chrome or safari on Windows. My problems start when I go to the Ipad and I try execute it. At begining the application is running but after when i try do a specific action on the application the browser is down !... The same happend with chrome on ipad. How can i find the problem with my application? Bellow you can see one log file from Ipad. In my personal opinion some javascript function is not doing a right job when this is running on the ipad (perfomance problems?). Any ideas?

Note: I have the same post on http://stackoverflow.com/questions/14901261/asp-net-mvc-sencha-cause-problems-ru nning-on-ipads

here you are the log of ipad..
