java memory leak detection

Original address: http://www.javatang.comA period of time on-line after the system upgrade, there is a serious high CPU problem, so began a series of optimization processing, now the process into a series of articles.Basic conceptsWhen analyzing a Java memory leak, you need a dump file that records the memory footprint

, the next is to open the Code project for White-box transformation, the corresponding code optimization (not within the scope of this article.) Some of the PID inconsistencies in the diagram are not tangled, some of the system restarted again.For more content please visit the starting blog http://jenwang.meFurther communication:-Email:[email protected]-For some topics of this blog interested in, hope to further exchange, please add QQ Group: 2825967-more technical exchange sharing in the Circle

application and calls hooks Based on win APIs. 12. sapmemory analyzer-is an open-source Java memory analysis software that can be used to help find memory leaks in Java programs. It is easy to find large memory blocks and verify who is occupying it all the time, it is base

When you make sure that you use Performance Monitor and use BoundsChecker, the program's operating environment and operating methods are the

Today I stumbled upon a Java memory Detection tool: Jstat A search on the Internet, the parameters are as follows Used to determine if there is a memory problem with the JVM. How to determine if the JVM garbage collection is normal. The general top directive basically doesn't meet this requirement because it mainly

This article introduced a simple use of Linux system Tools Valgrind to detect memory leaks by applying Valgrind to discover the memory problems of Linux programs, This paper implements a tool for detecting memory leaks, including the principle description and implementation details. the　　 both articles are from the IBM community (suggested to read the original te

Flexibility and freedom are a major feature of the C/C ++ language, which poses a challenge for C/C ++ programmers. When the program becomes more and more complex, the memory management will become more and more complex, and memory problems will occur if you are careful. Memory leakage is one of the most common memory
