Please help me.?

Thank you

Are you doing anything excessive with the dom? Like do you have 1000 listview items. Or perhaps a huge multi-page JQM document. — codaniel, Apr 27 '12 at 06:54
@codaniel No. But my sqlite database is pre populated database and which has more than 4000 thousand records. — stay_hungry, Apr 27 '12 at 06:59
Oh I think there is a limit. Do you know how much is in there? — codaniel, Apr 27 '12 at 06:59
Hmm I think the limit is 5mb. Anything else abnormal? Like how big is your index.html? — codaniel, Apr 27 '12 at 07:07
index.html is 6 kb . Is there way to increase database limit? — stay_hungry, Apr 27 '12 at 07:11

Switch the phone off and back on again. Then run via Xcode again, and see if the message is gone. If it's gone, then you or the phonegap libs probably locked up some memory.

I have tried this and this was fixed.. But after sometime it displays again Received memeory warning. – stay_hungry May 22 '12 at 02:43
Make sure you are using the latest version of Xcode, and then check if you are getting LLVM related warning messages (click the triangle toolbar button with the exclamation mark in it). If you do, it should give you and option to automaticcally apply fixes. After doing this, mine seems fine, but I can't guarantee it will be a fix. – Jack May 22 '12 at 06:30

By default Xcode uses the "Apple LLVM" compiler, but PhoneGap uses "LLVM GCC". One of the differences between them is the way they do memory management. I'm not an expert in this, so you'll have to read about it, or play with your Build Settings. Keep an eye on warnings - they are there for a reason ;-) – Jack May 22 '12 at 06:53
Hi, as a last note, follow the advice given here to get rid of warnings. You should still use the "Apple LLVM" compiler, but should turn of automatic reference counting: http://stackoverflow.com/questions/7006593/ipad-testing-of-phonegap-application-issues-in-main-method – Jack May 22 '12 at 07:28
If an app is exited, all memory associated with that app will be released to the system (barring an OS bugs which is exceedingly rare). – bbum Jun 30 '12 at 19:35

The issue will still reside with your Application, the only reason it will work on the iPad 2 and 3 is because they have more memory.

I would suggest you look into Memory Management within your wrapper as you cannot rely on hardware to cover up flaws in software - as if you continue down the track it will only get worse.

Because your iPad has comparatively more memory size. – Prabhu Natarajan May 14 '14 at 10:33

"Received memory warning" means that you are using too much memory.

To fix this, you should modify your program to use less memory.

Yes, this answer was somewhat facetious. However, without any code, any architectural information, any user interface information, or any other details, this about as good of an answer as you will get.

There are any tool to view memory leak? – stay_hungry Apr 27 '12 at 06:19
Haha now why couldn't I think of that answer? – codaniel Apr 27 '12 at 06:29
@codaniel I am using Javascripts. How can I modify my program to use less memory. – stay_hungry Apr 27 '12 at 06:47
