In other cases, and for long-lived applications in particular, the message might be an indication that we’re unintentionallyholding references to objects, preventing the garbage collector from cleaning them up.This is the Java language equivalent of a memory leak. (Note: APIs called by an appli...
Memory Management in the VM Container). If a shared closure is created, the valueJava Heap allocated sharedis increased accordingly. Shared closures that are old, no longer referenced, or flagged for deletion are removed by the shared garbage collection (seeFunctions of the Shared Garbage Collecto...
Occasionally people ask me how the garbage collectors work and what the differences are.JScript uses a nongenerational mark-and-sweep garbage collector. It works like this:Every variable which is "in scope" is called a "scavenger". A scavenger may refer to a number, an object, a string, ...
How Java Garbage Collection Works No matter what implementation of the garbage collector we use, to clean up the memory, a short pause needs to happen. Those pauses are also calledstop-the-worldevents or STW in short. You can envision your JVM-based application’s working cycles in the foll...
Disclaimer: This is the first time I have worked on a garbage collector so some of this may be incorrect. Corrections/cleanups are welcome. --RobertGabrielJakabosky "While working on this patch I had to learn how the garbage collector in Lua works. I am writing this to help me later if...

How the PHP session garbage collector really worksPreviousNext Sessions in PHP are easy to handle, but have a tricky configuration underneath. The common opinion is, that when you close your browser, the session is gone. Actually, it’s a little bit more complicated: Have a look on these ...

Mono Runtime The runtime implements the ECMA Common Language Infrastructure (CLI). The runtime provides a Just-in-Time (JIT) compiler, an Ahead-of-Time compiler (AOT), a library loader, the garbage collector, a threading system, and interoperability functionality. ...
What Are Garbage Collection (GC) Logs Thegarbage collector logis a text file produced by the Java Virtual Machine that describes the work of the garbage collector. It contains all the information you could need to see how the memory cleaning process works. It also shows how the garbage collect...
