I'm trying to open the following URL in iPad 3 Safari browser. http://www.pearsonschool.com/index.cfm?locator=PS1yJe&PMDbProgramId=110081&sampleId=11241

And doing the following steps:

Click on "Explore the innovative technology of Teacher Place for yourself" On the top left, click on "Dash" -> Teacher Content Then select CMP3 Grade 7 Click on Accentuate the Negative Then click on "3" (Multiplying and Dividing..) Select "Problem 3.1" Click "Launch" button

Here we have 3 options to expand viz Launch Video, Connecting to Prior or Knowledge and Presenting the Challenge. Expand all the 3 items by clicking ">" button on right of these options. Scroll to the bottom

It crashes.

Its working fine on iOS 5 Safari. But its crashing on iOS 6.0.1 Safari.

The following is the message that I noted during crash:

??Jan 31 07:21:13 Happiestminds kernel[0] <Debug>: 008192.238887 wlan.A[568] AppleBCMWLANNetManager::checkRealTimeTraffic():  now 8192.238881625 num entries 4

I couldn't understand why is it crashing in latest safari.... When googled, i found that some URL's saying its problem related to Redirections, some say about bookmarking and some say about memory management. But I couldn't find the exact issue.

Can some one help me in identifying the exact issue please?

You can try to debug the javascript using chrome on mac, add console.log to your code and follow this tutorial:

http://devcoma.blogspot.it/2014/03/how-to-investigate-ios-safari-crashes.html

I've used a proxy installed on my mac in order to debug and trace from ios safari to the chrome dev tools.

I found that on my web app safari crashed when using iframes, css transitions, css overflow property and, the jQuery ready event, not all at the same time, obviously.

As and when there's updates in the browsers, we have to change the javascript etc respectively in the code as well.
