I've got a headless ARM-based Linux (v3.10.53-1.1.1) system with no swap space enabled, and I occasionally see processes get killed by the OOM-killer even though there is plenty of RAM available. ...

I'm a little bit confused. In the OS course we were told that all OSes take care of memory fragmentation by paging or segmentation and there is no contiguous physical memory allocation at all...

I have a C# 4.0 application (single producer/single consumer) which transfers huge amount of data in chunks. Although there's no new memory allocation I run out of memory after a while. I profiled...

I am running a C# application that services HTTP requests. I have noticed recently that it's taking up more memory then I expect. I grabbed some dumps, popped them in Windbg, and found that most of...

I ask this question to determine which memory allocation algorithm gives better results with performance critical applications, like game engines, or embedded applications. Results are actually dep...

Short background: I'm developing a system that should run for months and using dynamic allocations. The question: I've heard that memory fragmentation slows down new and malloc operators becau...

When I use malloc()s and free()s randomly, nested and with different sizes, at some point the memory will be fragmented because these operations leave a large list of small memory areas behind that...

For both on-heap and off-heap allocations. On-heap - in the context of three major garbage collectors: CMS, Parallel Old and and G1. What I know (or think that I know) to the moment: all object ...

In my program I see some resident size increase. I suppose it is because of heap fragmentation. So I am planning to use #pragma pack 1. Will it reduce the heap fragmentation? Will it be having som...

What are the various mechanisms using which we can detect if a process execution is leading to memory fragmentation? Are there any tools available for the same? Suggestion for tools which work wi...

I'm constantly running slowly out of memory. I've used WinDbg to have a look at the memory dump and this it what it looks like: 000007f975ee0630 557377 41027736 System.Object[] 000007f975f004d0 18...

I am using ANTS memory profiler to diagnose an increase in memory leak I am facing in one of my .NET 2.0 applications. I took 7 snapshots of the process over a period of 7.5 hours, and here is a ta...

We're using C++ in an embedded system environment and basically don't want any kind of dynamic memory allocation (see for example Resources for memory management in embedded application for the kin...

Could someone please tell me why following things could happen: I have 2 computers: my working comp Server I maintain C++ program (msvc 2005 c++ compiled) that works too slow only on server, ...

I'm trying to allocate some memory but sometimes get error "out of memory". cudaMemGetInfo says that available more memory that I need. So, problem in memory fragmentation. Is it possible to fix th...

I'm working on a large server application written using C++. This server needs to run possibly for months without restarting. Fragmentation is already a suspected issue here, since our memory consu...

In a 32-bit machine each process gets a 4GB virtual space. In this case one can worry that we might face trouble due to fragmentation. But in the case of a 64-bit machine we theoretically have a hu...

I am toying with certain caching algorithm, which is challenging somewhat. Basically, it needs to allocate lots of small objects (double arrays, 1 to 256 elements), with objects accessible through ...
