java memory leak

(private type) I guess: According to the Microsoft Framework's custom, there must be properties or methods to set this thing. --I think too much, I have been looking for a long time can not find the relevant method. Universal Solution: Anti-compilationThere must be a way to fix this data until the data is there.Reflection is omnipotent--but I don't want to use it.Then, start the decompile: see directArenas where the field is assigned, and where to add the data.Problem solvingRun th

In a previous blog post Linux kernel module, a way to find out about memory leaks >> , I introduced a method of finding kernel memory leaks. This is a few months, and customers complain: using the product 5 days or so, the SUSE server due to memory exhaustion and crash. O my God, don't, run on my machine good WOW (programmers commonly used sayings hehe). So let'

In fact, memory leaks have always been a headache, and this has been a big improvement in the language with the GC, but there may still be problems.First, what is memory leak (leak)?Memory leaks do not mean that memory is not brok

Valgrind is a memory debugging tool for Linux (x86, x86_64, and PPC32) programs that can monitor memory usage of the compiled binaries (malloc and free in C, and new and delete in the C + +). Identify memory leak issues.The Memcheck tool included in Valgrind can check for the following program errors:Using uninitialize

First, what is memory leak (leak)?Memory leaks do not mean that memory is not broken, or memory is not plugged in, simply, memory leaks is in the time you expect your program to occupy

When it comes to memory leaks, most programmers smell the color change. Yes, memory leaks are easy to introduce, but difficult to locate. Take your My phone as an example (assuming not often shut down), if you leak some memory every day, then the beginning of one weeks, you will find that the mobile phone good, when th

some deadlock resource competition problems. No Deadlock report is displayed, but most of the suspicious operations are waiting for the monitor problem. I have read that most of the sleep threads are stuck on java. util. Vector. This should be the underlying problem caused by some IO operations.

pointed to by any reference, and the object is recycled when it is discovered by the GC, and if a set of objects contains only references to each other, and no references from outside them (for example, two objects A and B hold references to each other, but no external objects hold references to a or b), This is still not reachable and will be recycled by GC.Damage to memory leaksThe danger of a memory

One of the most troublesome problems in C/C ++ development is memory management. Sometimes it takes several days to find a memory leak or a memory access out of bounds, if there is a tool that can help us do this, valgrind is such a tool. Valgrind is a software suite based on a simulated program debugger and analyzer

1. Static analysisWith static analysis, we can get the most initial insight into some of the code's non-canonical places or memory leaks, which is our first step in detecting memory leaks. Of course, there are some warnings that we don't care about to skip.2. Check for memory leaks with instrumentsThis method can roughly locate where we have a

Almost every programmer encounters a memory leak in the process of development, so how do we detect where the app is going to have a memory leak? Square has unveiled a simple and crude tool for detecting memory leaks-leakcanaryWhat is a
