out-of-memory

问题 Curious about what was the maximum string length I could get in Javascript, I tested it myself, today, on my Firefox 43.0.1, running in Windows 7. I was able to construct a string with length 2^28 - 1 , but when I tried to create a string with one more char, Firebug showed me the "allocation size overflow" error, meaning the string must be less than 256 MB. Is this the same thing for all browsers, all computers, all operational systems, or it depends? I created the following snippet to find

问题 We are working on a business application (1 million+ LOC) developed since 10+ years. While switching to JDK8 we get an issue with the metaspace of JDK8. This seems to be related to the JaxB-Version referenced in com.sun.xml.ws:webservices-rt:1.4 (Metro 1.4). Because of the intense linking in the application and legacy creation of classes/instances via JaxB it isn't simple to switch on the fly the old libraries. Currently we are researching this issue. We created a sample programm that

问题 I'm using Filestream for read big file (> 500 MB) and I get the OutOfMemoryException. Any solutions about it. My Code is: using (var fs3 = new FileStream(filePath2, FileMode.Open, FileAccess.Read)) { byte[] b2 = ReadFully(fs3, 1024); } public static byte[] ReadFully(Stream stream, int initialLength) { // If we've been passed an unhelpful initial length, just // use 32K. if (initialLength < 1) { initialLength = 32768; } byte[] buffer = new byte[initialLength]; int read = 0; int chunk; while (

问题 I have a large .xlsx file (141 MB, containing 293413 lines with 62 columns each) I need to perform some operations within. I am having problems with loading this file ( OutOfMemoryError ), as POI has a large memory footprint on XSSF (xlsx) workbooks. This SO question is similar, and the solution presented is to increase the VM's allocated/maximum memory. It seems to work for that kind of file-size (9MB), but for me, it just simply doesn't work even if a allocate all available system memory.
