I've been running into a peculiar issue with certain Java applications in the HP-UX environment.
The heap is set to -mx512, yet, looking at the memory regions for this java process using gpm, it shows it using upwards of 1.6GBs of RSS memory, with 1.1...

In general, only the data in Java objects is stored on the Java heap, all other memory required contiguous chunk allocated....
By the Java VM is allocated from the "native" or "C" heap (in fact, the Java heap itself is just one.

I know there is no "right" heap size, but which heap size do you use in your applications (application type, jdk, os)?

Major collection with a large heap size can take >10 mintues (on unoptimized GC applications).....
A native application can usually use as much heap as it wants, until it runs out of virtual address space large heap sizes.

Is it possible to view the heap and stack during debugging?

For native C++, the Autos window displays function return values as well.
And for the Heap and the preceding line of code.
You can view the function or procedure calls that are currently on the stack .

I have a .NET/native C++ application. Currently, the C++ code allocates memory on the default heap which persists for the life of the application. Basically, functions/commands are executed in the C++ which results in allocation/modification of the current...

A heap is created by lower-level system....
It is a user-level memory manager.
Heap is a sort of big chunk of memory.
Just an idea!
From MSDN's Heap to the system.
It was a while ago), and you might be able to take advantage of it .

We have weird memory leak problem with a Java process running in linux has an ever growing swap usage. So naturally we looked at the heap dump and also used a profiler to monitor it over a period of time. We found that

Doesn't the case where 1) the process's heap space does not change but 2) the swap usage does if a Java process's own heap usage does not change but the swap usage does, that would seem could be leaking something in native memory,....

Is there a way in the .NET API to iterate on the managed objects present in the managed heap?
We would like to add a routine at some points in our program which checks the presence of some objects in the managed heap.

I need to detect whether the file I am attaching to an email is exceeding the server limit. I am not allowed to increase the JVM heap size to do this since it is going to affect the application performance.
If I don’t increase the JVM heap size, I will...

You can do this by calling map.
However that sounds a painful way without actually reading / allocating space in the heap.
You could allocate the memory natively via native code and JNI.

Are there any heap data structure implementations out there, fibonacci, binary, or binomial?
Reference: These are data structures used to implement priority queues, not the ones used to allocate dynamic memory. See http://en.wikipedia.org/wiki/Heap_(data...

I found two implementations of binary heap ( link 1 , link 2 ) and one implementation of binomial heap in f# ( link.

I don't know of any native framework implementation.

Is the a VS2005 C++ compiler flag like the Xmx???M java flag so I can limit the heap size of my application running on Windows.

Alternatively block.
The heap size-provided malloc() or new operator) you can artificially limit the heap size that way.
It can do a lot of other interesting things with the heap of native applications.

When you create a new object are allocated on the heap.....
However, the implementation of allocable memory isn't quite like the way the heap is implemented in the C/C++ model.
For the object is allocated in what passes for the heap.
