Q: iPad Safari crashing regularly

Crashed my Safari on Gizmodo for me too. I connected iPad to my mac and run Xcode and went to Console, where I can see all error messages in real time, and here what I saw when I started Safari and open a web page:

So, basically we can see that as I open Safari, it gives warning about memory and starts killing background application abnormally (with signal 9).

and when it crashes, it writes to Console the following:

hope they will fix it in 5.1, which will come out sooner or later.

Yep that site did it for me. Good to be able to demonstrate the issue if/when i get to a genius!

Atomic Browser handled the site ok......Not so Safari.

You are right, Atomic browser is OK, but in Console I still see a lot of errors and warning about low memory:

Not on my ipad 2 running ios 5 (not 5.01). Just to let you know this isn't an OS 5 bug.

Wow, 28 pages of replies and 132,000 views on just this thread alone. You boys at Apple got the hint yet? This constant crashing is driving everyone NUTS and it's been going on for months. You guys have an ETA on a fix for this thing or what? Safari crashed TWICE just getting to this page.

Representing a hundred unhappy users out of millions and millions of iPads in use today.  Sure is impressive.

There are no 'you guys' here.  Just us users like you.  Apple NEVER responds in these forums.  They moderate but that's all.  No one here knows when or what Apple is doing about this issue.

http://www.apple.com/feedback/ipad.html

Please contact tech support and do what they say. A DFU restore is not the solution, apparently. So determine what is. Only tech support or the genius bar will have the answer.

That page listed earlier does not crash my ipad's safari. (Gizmodo) An earlier example (Google+) does.

After reading this forum, I tried something that was suggested and it has gone MADE AN ENOROMOUS difference. A few people suggested turning on debug mode in Safari and the advanced preference panel. I did and this is the first time in two months that Safari has not quit every two minutes!!!!!!!

Ever since upgrading to ios 5.0 then 5.0.1 my iPad has been the worst computing experience of my life. I tried resetting and restoring multiple times. I tried everything!!

FINALLY, on suggestions found here I turned on the Safari debugger and I can finally use my iPad again with out random  and frequent crashes and slow downs. If you are still having problems give it a try.

Honestly, Apple should be ashamed of how bad an experience this is for all of us!!

I'm really glad this worked. I also wanted to remark that if other non-safari browsers are not crashing, then it's either not a webkit problem, or something in the way Safari is handling exceptions, which turning on debug mode fixes.

Howwver, given that I'm not having the problem on my ipad 2 or iphone (in fact there are zero reports of it happening on other devices on this thread), it seems to be confined to a few devices, which makes it puzzling. Other people reports that a hardware replacement does minimize the issue. Does a developer want to comment on what happens when you turn on debug mode?

Hi,

What the heck is MobileMail and why is it the first thing to be killed? Is that the mail client? Does it kill in any particular order or with any reason to it?

This is also a problem on the iPad 2. Mine crashes a lot after the update to 5.x. In addition to Safari crashing, other web bowsers I installed also crash. Even mail occasionally crashes. Turning on debug in safari appears to have improved it somewhat. Perhaps people can start posting their iPad details to see if any trends.

Mine is an iPad2, 16GB, with AT&amp;T 3G, OS ver 5.01.

As a developer I am experiencing this issue too.... The site I'm working on http://www.ionsonic.com (recently) started to crash  iPad's Safari browser constantly. This is a real pain....  as any developer will tell you until you find the problem you generally go around thinking the issue is with your work and your code. But happily once again after extensive debugging this appears not to be the case. Why? Well  Safari on the iPad appears to have an iframe issue or a bug. Here's the detail. If the social network plugins for the facebook like, twitter tweet and google plus buttons are disabled on http://www.ionsonic.com the site remains stable, it does not crash the browser. Enable any one of the social plugins bringing an iframe back onto the page and the site once again crashes the browser constantly. Therefore to me it looks like there is a issue with Safari's mechanism for handling iframes, in my case iframes embedded by the social network plugins   on website pages. Hopefully this will help somebody find and fix the issue.

With social network plugins essentially everywhere today anybody or any company supplying a browser for consumption by the general public needs to add a couple of iframe and social network plugin test cases to their testing schedule to catch issues like this.

Presumably you have sent this information to Apple as well as posting it in this user-to-user forum?
