VisualVM VS Valgrind

If you're curious, attach VisualVM and watch the RAM usage graph. You'll notice that Java performs garbage collections long before reaching allocating the maximum amount of RAM allocated, and you can't even feel any performance issue in-game. Source: 11 months ago

Hangs and deadlocks are significantly harder to debug. A first step is taking a thread dump so you can see what each thread in the JVM is currently trying to do. I like VisualVM for this, you can also use the command-line tools jps -l (to list all Java PIDs) and jstack for taking a thread dump. Source: 12 months ago

The Java VisualVM project is an advanced dashboard for Memory and CPU monitoring. It features advanced resource visualization, as well as process and thread utilization. - Source: dev.to / 12 months ago

This sounds like a server thread freeze/deadlock/crash or something. I think I would start debugging this using a tool like VisualVM; attach it to the game, wait for the hang, take a thread dump, and check what the server thread is up to. Source: about 1 year ago

Just wanted to chip in to say that /u/UtilFunction is correct. The proper way to measure memory consumption of any Java application independent of which garbage collector is used is to perform a heap dump (which automatically forces a complete garbage collection). I like to use VisualVM for that. Source: about 1 year ago

Continuous Integration and Continuous Deployment [CI/CD] pipelines play a crucial role in enforcing code quality, especially when working with memory-unsafe languages. By integrating automated dynamic analysis tools like Valgrind or AddressSanitizer, static analysis tools like Clang Static Analyzer or cppcheck, and manual code review processes, developers can identify and mitigate many memory-related... - Source: dev.to / about 1 month ago

Valgrind is an open-source tool designed to help developers identify memory management issues, memory leaks, and various other types of memory-related errors in their programs. It's commonly used for debugging and profiling purposes, particularly in C and C++ development. Here's an overview of Valgrind:. - Source: dev.to / 2 months ago

Valgrind is a tool for debugging memory errors. We have it installed on our linux machines at work. I'm not sure how difficult this is to install and setup. You can find more info here: https://valgrind.org/. Source: 5 months ago

It's often best not to think too much about "aesthetic", or performance, at first, and to focus instead on getting something that works, correctly. FWIW, The Mythical Man-Month[0] recommends to start with a few throw-away prototypes, during which you're gaining expertise over the problem, that you can later crystallize in more definite versions. Now, it doesn't mean good practices should be discarded... - Source: Hacker News / 7 months ago

I think you're on the right path, yes. Usually I use Valgrind for all memory related debugging, not sure if it can help you here. Source: 10 months ago
