ios low memory crash but very low memory usage


ios low memory crash but very low memory usage  using -'iphone,objective-c,ios,ipad,memory-management'

This has been annoying me for a long time. My app runs taking up about 2.74MB of memory.  That's fine. But then when it creates a UIWebView it goes up to around 5.87MB and proceeds to crash. Those are the values given under Live Bytes in Instruments while running on my 1st gen iPad.

There is no crash log that I can find.  The following is from the console:

MyApp[1205] <Warning>: Received memory warning. Level=1
MyApp[1205] <Warning>: applicationDidReceiveMemoryWarning
SpringBoard[30] <Warning>: Received memory warning. Level=1

I have removed all calls to imageNamed, changed autoreleased stuff to alloc/release. But I cannot work out why this is happening and it's driving me insane.

Thanks for any help!
