Contrary to what many developers believe, the amount of RAM that's installed doesn't impact the possibility of an OutOfMemoryException. A 32-bit operating system can address 4 GB of virtual address space, whatever the amount of physical memory that is installed in the box. MC-79003 Minecraft 1.8.3 on Mac OS X blocked after a few seconds. Resolved; MC-79559 Tesselating block model. Resolved; MC-81027 crashed report. Game will not start up. An OutOfMemoryException exception has two major causes: You are attempting to expand a StringBuilder object beyond the length defined by its StringBuilder.MaxCapacity property. The common language runtime cannot allocate enough contiguous memory to successfully perform an operation.

Everwind mac os. While programming for my web app the other day, my application threw an System.OutOfMemoryException when initializing a list of objects. To me this seemed pretty much impossible because my machine has 4GB RAM. Specifically the error happened when I tried to add an existing collection to a new list. For example:
My original thought was that this assignment shouldn't allocate much memory since the shapes from my list should already exist inside memory. The Shape class is a complex object and I was trying to assign about 25,000 items to the new list at once. We should also note that the total size of all Shapes in the application come from a database that is only about 250MB in size. At first I was stumped and had no idea what may be causing the System.OutOfMemoryException.
What happened
- If you are running a 32 bit Windows, you won't have all the 4GB accessible, only 2GB per object array. This is a limitation of the .NET framework. (This happened to be my issue, as my shape array was greater than 2GB after debugging.)
- Don't forget that the underlying implementation of
Listis an array. If your memory is heavily fragmented, there may not be enough contiguous space to allocate yourList, even though in total you have plenty of free memory.
Solutions
- If you are running on 64 bit Windows and you have enough free memory, ensure that the platform target is set correctly in the project properties > build properties.
- If you are using .NET 4.5 or greater you can add this line to the runtime section of your App.Config:
Remember that data stored in the database compared to in memory is very different. Use this C# snippet to observe how much your memory is changing as you load the object(s) into memory.

Initializing an array which is not large enough, ensure the array size is correct!This is by far the most common cause of this exception.
Reading very large data sets into memory, as demonstrated in the example above.
Having too many active sessions or storing too much data in session state.
Applying a complex regex (regular expression) to a large file or string.
Downloading, streaming or uploading large files.
You are calling the StringBuilder.Insert method and are repeatedly concatenating strings.

You are not implementing the Implementing a Dispose method when dealing with unmanaged resources, and your app is leaking.

You are storing very large sets of data in memory. An example could be querying large database data sets via LINQ in memory.
