Recursive functions:A recursive function is a function that calls itself indirectly or directly to repeat an/ certain set of instruction(s) until a certain condition(s) is/are met. If these functions are well-designed, they will likely lead to memory lead and, eventually heap of memory error...
There is no easy or very reliable way to identify the amount of actual memory being used by an individual process or program or application because every process will be using multiple system maps from various libraries like glibc which will also be used by many other processes so the reported...

Heap overflow: It occurs when the memory allocated dynamically by the program exceeds the heap size. A heap is a first in first out (FIFO) data structure used to store data that is required for a long time during program running. When the heap overflows, even if the program does not st...
There are two types of buffer overflows in general: stack-based and heap-based. In this tutorial, we’ll discuss how to activate and deactivate stack-based buffer overflow checks in Linux using gcc and clang-11. 2. Code Example We’ll use the following C program, buffer_overflow.c: #...
If you find that after truncation and a full restart of the cluster services you have a stable system, you can use find to locate all 0-byte files and remove them. While relatively safe, this is not recommended unless you are actually running out of inodes. You can check this by ...
The recommendation is to usejstack. SeeOption 5:jstackLinux script(continuous). JBoss Fuse 6 If you are capturing thread dumps from a child container, note that the process is different to the root container. Be sure to check the process ID (PID) using 'ps' or similar before selecting the...
If you want to improve your JVM and GC tuning skill then you should check out Java Performance The Definitive Guide By Scott Oaks, one of the must-read a book for experienced Java programmers.Increasing Heap Memory for Java Program Running on Eclipse...
The next line tells you the GC had 21mb reported to the OS as memory it manages. The very last line tells you that the bookkeeping structures in the runtime + the managed heap take ~60 MB. This means two things might be happening: 1) there's some native memory that we don't ...
