and external modulesThe reference to the inner class is a relatively easy one to forget, and once it is not released it can cause a series of subsequent class objects not to be released. In addition, the programmer should be careful of the external module inadvertently reference, such as programmer A is responsible for a module, a method called the B module, such as: public void registermsg (Object b); This call will be very careful, passing in an object, it is likely that module B will maintai

folder to open, choose to connect--tomcat--memory, you can start to monitor the JVM memory recycling situation, after a period of monitoring, found that the Laosheng generation of memory recovery exists exception.As can be seen, each recovery of memory is less than the last

Review A memory leak (memory leak) refers to a program failing to release memory that is no longer in use due to negligence or error. So in Android, when an object holds a reference to an activity, and if the object cannot be reclaimed by the system, the activity is not rec

Test a business data portal for functional testing of the Task manager, found that the IE process has reached the 423,145k, suspected of a memory leak, so I intend to use IE plug-in JS memory leaks dector to detect, However, after some operations that could cause memory leaks, the test results were always normal and no

VLD Introduction Due to the lack of the so-called garbage collector, the allocation and release of memory need to be controlled by the programmer, which will bring some difficulties to C + + programmers. As your program becomes more complex, its memory management becomes more and more difficult. Memory leaks and memory
