out-of-memory

I'm getting a java.lang.OutOfMemoryError: Java heap space even with GSON Streaming. {"result":"OK","base64":"JVBERi0xLjQKJeLjz9MKMSAwIG9iago8PC...."} base64 can be up to 200Mb long. GSON is taking much more memory than that, (3GB) When I try to store the base64 in a variable I get a: Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2367) at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:130) at java.lang.AbstractStringBuilder.ensureCapacityInternal(AbstractStringBuilder.java:114) at java.lang

I have tried to create nested recyclerview in combination with the mvvmcross-framework which actually worked quite easily, but now I'm getting out of memory exceptions. Scenario I have a list of around 3000 entries with complex and long names, which are divided by 8 categories. The user can select the entries via a checkbox to assign them to a task later on. Even if it might sound like there are too many entries, it is actually quite easily to navigate through them, if the user has some background knowledge, so I would rather not change it at this point. Code First the simplified data models

I am working on a 64-bit .Net Windows Service application that essentially loads up a bunch of data for processing. While performing data volume testing, we were able to overwhelm the process and it threw an OutOfMemoryException (I do not have any performance statistics on the process when it failed.) I have a hard time believing that the process requested a chunk of memory that would have exceeded the allowable address space for the process since its running on a 64-bit machine. I do know that the process is running on a machine that is consistently in the neighborhood of 80%-90% physical

I'm fairly new to programming and am working for my dissertation on a web crawler. I've been provided by a web crawler but i found it to be too slow since it is single threaded. It took 30 mins to crawl 1000 webpages. I tried to create multiple threads for execution and with 20 threads simultaneously running the 1000 webpages took only 2 minutes. But now I'm encountering "Heap Out of Memory" errors. I'm sure what i did was wrong which was create a for loop for 20 threads. What would be the right way to multi-thread the java crawler without giving out the errors? And speaking of which, is multi

I have a piece of software that has to analyze big files. Constraining the input or giving infinite memory is not an option, so I have to live with flying OOMEs. Because the OOME only kills the Thread, my software runs in some crappy state. From outside everything looks okay because the process is running but on the inside it's braindead. I would like to pull the plug on it. But how can I do this? Catching a OOME does not guranteee that the next line of code will be executed. e.g System.exit(9). So the JVM has to notice OOME and destory itself. Is their some vm option for this? When you get an

I am running a code for long hours as part of a stress test on an Oracle db and using java version "1.4.2". In a nutshell, what I am doing is : while(true) { Allocating some memory as a blob byte[] data = new byte[1000]; stmt = fConnection.prepareStatement(query); // [compiling an insert query which uses the above blob] stmt.execute(); // I insert this blob-row in the database. stmt.close(); } Now I want to run this test for 8-10 hrs. However apparently after inserting about 15million records I hit the java.lang.OutOfMemoryError I am running this with -Xms512m -Xmx2g . I tried using higher
