Q: Ipad air low memory crash

I just wanted to add that no one here nor me is claiming every ipad air to be perfect. However, there are those of you claiming every ipad air to be broken. So think about it, who's being more realistic?

The crashes have been reproduced by at least three forum posters on numerous - if not all - showroom floor devices inside Apple stores. I appreciate that you have a data point that exists outside the realm of believability and it is not obvious to me that you have 1GB of RAM. Because your data point is so far-fetched, your device should probably go in for thorough investigation on why it is one of the very few devices in existance that are not affected.

My previous iPad mini (gen one) has only half the RAM of my iPad mini w/retina, yet the gen-one device performed 'rock solid' in comparison on the same iOS revision (I had the gen-one on 7.0.4 before it was sold). 64bit processes do consume more RAM than 32bit, but it's not double. The overall experience on the mini retina should be far smoother, and it isn't.

Yes, that's it. Keep repeating yourselves until the only sensible posts are faaaar from view.

Lets make this an analogy maybe that will get our point accross about the 64bit processors compared to 32 bit, oh and side note 64 bit processing does require more resources and yes i know im showing window specs

If you want to run Windows 7 on your PC, here's what it takes:

•   1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor 
•   1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit) 
•   16 GB available hard disk space (32-bit) or 20 GB (64-bit) 
•   DirectX 9 graphics device with WDDM 1.0 or higher driver 

the processors is the engine of a car, it supplys the power,  the ram is the transmission it what gets it to go if you double the power output of the engine(or processor) and still use the same transmission you arent going to go anywhere any faster and run the risk of breaking something.   so yes the iPad airs have a design flaw as more and more 64 bit apps come out.  Its like trying to fill a pool with a garden hose.

Think of it like this, lets use your own analogy. This isnt an ordinary engine off the shelf, this is an optimized machine. Same rules do not apply.

I just popped in to suggest something. What if Safari is not crashing?

What if the normal usage of Safari causes your system ask Safari to close (not nicely ask, force kill the app), along with many other running applications?

Try this:

Open 'Maps', get directions, and start the trip.

If you press the home button, you still have a blue bar along the top for navigation. Open Safari, still see a blue bar (Maps is active). Reproduce the crash through Safari and let me know if you still see that blue bar.

What is slightly hilarious is that since, you know, all these devices are are overgrown mp3 players... apps that use audio do not receive the SIGKILL message. The stock Music app does not get terminated and neither does Nanostudio (background audio enabled).

Looking at the diags, there is a long list of apps that get the SIGKILL message (these have the vm_pageshortage notation to the right of them), but audio seems to be spared. Which is good, I like my tunes!

"64bit processes do consume more RAM than 32bit, but it's not double"

Ridiculous statement. 64 0r 32 is the datapath width.

@nothinghurtstheblob...  Holy crap the navigation never got the kill command

@ lexschellings...  I never said 64bit processing uses double the ram, it was simply using it as an illustration that most platforms that run 64 bit processing require double the ram so there is some wiggle room

@ humans   yes these are optimized machines, so is the 496 big block in my truck, its "optimized to go faster give more power and last longer ( just like apple claims on thier website about the ipad air)  the problem is I blew up my stock transmission after 50 miles on the new motor, it wasnt strong enough to handle the more power.  

As people have said before there is a limiting factor in the ipad air running 64 bit architecture it is the ram, as people have said before these issue probably wouldnt be as numerous if there were 2gb of ram instead of 1.

Even apple says the Ipad air is ...  A7 chip, Desktop class architecture, no desktop required.   Let me ask you what desktop today runs on 1gb of ram?

You silly humans = broken record....skip, repeat, skip, repeat, skip, repeat, skip, repeat

Would you post that crashlog? I'm curious if the process was flagged (audio) or just got skipped by the vm_pageshortage flag altogether.

It is under Settings -> General -> About -> Diags & Usage -> Diags and Usage.

Moving to a larger memory address space increases the size of pointers, which in turn can increase the footprint of 64-bit applications compared to their 32-bit counterparts. So although there’s clearly a performance uplift from app developers recompiling in 64-bit mode (more registers, access to new instructions), there’s also an associated memory footprint penalty. The iPad Air and iPhone 5s don’t feature a corresponding increase in memory capacity, so there is a big ?

Summarizing: 64bit = 30% more ram in respect of 32bit Apple devices...

Haha, yes. I'm the broken record. Not you guys, who keep whining over and over and over about the same thing. Interesting.

Thank you. I was disappointed to discover that the new devices had only 1GB of RAM, but that since I was accustomed to getting by on 512MB on the iPad mini gen-1, that even the 30% overhead for 64bit was not going to be a big deal - it should not be. More RAM could fix the problem, but I suspect that the underlying problem would still exist even with more RAM.

Wrong.

I agree with you...

Unfortunately there are two big issues as other users as already stated:

1-64 bit architecture needs more Ram and a more efficient ram handling...

2- iOS 7 is still immature and moreover is not optimized for 64 bit architecture..

Mix these factors an you will have our crash, reboots and so far...

The tricky part is you don’t really need all that much more memory, so the doubt is if OS optimization will handle the problems or not...if the improvement on the software side will be sufficient or not...

Ps: personally speaking: the nex gen iPads will come with two or more giga of Ram, and for us maybe Apple has though the following two scenarios:

-is your iPad crashing? NO: perfect, your iPad is perfect for you..

                                  YES: what a pity...you are a power user, so you need the new iPad pro with 2 gigas of ram...

And everything will be covered up....

However I hope to be wrong, and that at least in May I will post again on this forum just to say: guys iOS 7.1 has resolved everything, I love my air...
