Someone suggested I use pmap -x to see exactly what the memory is doing. The C\/C++ runtime will check its own datastructures for available memory, and if it doesn&#39;t have any, it will forward the call to the OS. If your application allocates memory, it will ask it to the C\/C++ runtime. A small range of memory that can be allocated (owned by the application), freed (owned by glibc), or combined with adjacent chunks into larger ranges. Giancarlo del Rossi (Red Hat) Photo by StockSnap on Pixabay Tools like ps and pgrep can help you learn about the processes running on your system. So, we change tool and use pmap -x [pid] and cat \/proc\/ [pid]\/smaps to see java memory usage. Note that a chunk is a wrapper around the block of memory that is given to the application.<\/strong><\/p>\n<p><figure> \t\t<img decoding=\"async\" src=\"https:\/\/image.slidesharecdn.com\/memoryleaksandperformanceangular-150304173138-conversion-gate01\/95\/javascript-memory-leaks-and-performance-angular-3-638.jpg?cb=1425490738\" alt=\"Javascript Memory leaks and Performance &amp; Angular\" style=\"width: 100%; padding: 5px; background-color: grey;\"><figcaption>Javascript Memory leaks and Performance &amp; Angular (Ina Hamilton)<\/figcaption><\/figure>\n<p> \t \t<strong>Pmap Anon Memory Leak<\/strong>. <strong>STANDARDS No standards apply, but pmap looks an awful lot like a SunOS command.
