I've been getting some OutOfMemory errors lately in my application. Is it possible to detect ahead of time when the virtual machine is running low on memory? In other words to preemptively deal with OutOfMemory errors before they actually occur? ...
mod_python(?) is eating a lot of ram (about 9mb per worker process). If i open several TRAC pages at once many of them will have an error due to no ram (64mb virtual limit). if i limit the worker threads to 3 i can get by alright. Problem is if no one is accessing TRAC i have A LOT of ram being unused. Is there a way i can either Limi...
I'm creating a linux program in C++ for a portable device in order to render html files. The problem is that the device is limited in RAM, thus making it impossible to open big files (with actual software). One solution is to dynamically load/unload parts of the file, but I'm not sure how to implement that. The ability of scrolling is...
I want to know which technique antivirus programs use for scanning disk or files and maintaining low memory consumption. They don't affect the user activity either. I am looking for an approach by which we can achieve disk scanning with low memory consumption. ...

I am able to load over 200 UIImage objects into a NSMutableDictionary without any memorry warning issues. When I start displaying them on the screen (after about showing 10-20 images) I get low memory warnings and an eventual crash. Only about 8 images are displayed at anyone time. Does it take additional memory to actually draw a UII...
I've got an app that caches a pretty decent amount of data in memory after parsing a csv file, and also displays an MKMapView. After scrolling across the country from one end to the other in the MKMapView, the app inevitably gives me one or more: Received memory warning. Level=1 Received memory warning. Level=2 and finally crashes due...
I have a subclass of NSObject, it is a singleton which loads a list of images into memory, either from hard drive or downloads them from the internet. I want to release the images stored in memory if the app recieves a low memory message, like in a UIViewController. (it then gets the images from hard drive when it next needs them). ...
