This is a contiguous memory block of five bytes, spanning from location 1 to location 5: It represents bytes (colored light blue) that are together in memory with no gap bytes (white) between them. This is a non-contiguous set of five bytes of interest: It is fragmented into three groups of bytes (colored yellow) with … Read more

If you want to use 32-bit references, your heap is limited to 32 GB. However, if you are willing to use 64-bit references, the size is likely to be limited by your OS, just as it is with 32-bit JVM. e.g. on Windows 32-bit this is 1.2 to 1.5 GB. Note: you will want your … Read more
10 int structs would be allocated on the the heap, only pointer to them would be on stack, correct? Yes, correct. How would one make fixed size array to go on stack? What if I’m using stucts I defined? The stackalloc keyword serves this purpose. However, this works in unsafe context only, which is a … Read more
According to the C11 standard, the relational operators <, <=, >, and >= may only be used on pointers to elements of the same array or struct object. This is spelled out in section 6.5.8p5: When two pointers are compared, the result depends on the relative locations in the address space of the objects pointed … Read more
just use this function to decode…this is perfect solution for your error..because i also getting same error and i got this solution.. public static Bitmap decodeFile(File f,int WIDTH,int HIGHT){ try { //Decode image size BitmapFactory.Options o = new BitmapFactory.Options(); o.inJustDecodeBounds = true; BitmapFactory.decodeStream(new FileInputStream(f),null,o); //The new size we want to scale to final int REQUIRED_WIDTH=WIDTH; … Read more
You don’t mention which build of the JVM you’re running, this is crucial info. You also don’t mention how long the app tends to run for (e.g. is it for the length of a working day? a week? less?) A few other points If you are continually leaking objects into tenured because you’re allocating at … Read more
I think I have discovered the error. I was using ‘service’ to run elasticsearch and therefore my environment variables got stripped. I had to update the /etc/default/elasticsearch file with the correcct env variables (specifically the ES_HEAP_SIZE=16g). So far it’s running well and app is not erroring.
Excerpts from Raymond Chen’s OldNewThing Back in the days of 16-bit Windows, the difference was significant. In 16-bit Windows, memory was accessed through values called “selectors”, each of which could address up to 64K. There was a default selector called the “data selector”; operations on so-called “near pointers” were performed relative to the data selector. … Read more
maxMemory() returns the maximum amount of memory that java will use. So That will not get you what you want. totalMemory() is what you are looking for though. See The docs
