The concept behind a fork bomb — the processes continually replicate themselves, potentially causing a denial of service. In computing, a fork bomb (also called rabbit virus) is a denial-of-service (DoS) attack wherein a process continually replicates itself to deplete available system resources, slowing down or crashing the system due to resource starvation.
ABAP Version was just an infinite loop and not a fork bomb. Given the fixed number of process slots Netweaver has with a roll-in/roll-out mechanism a forkbomb does not quite make sense - it would not bring the system completely to its knees, it would just drastically degrade performance. I guess a semi fork-bomb can be made using CALL FUNCTION ..
Fork and its variants are typically the only way of doing so in Unix-like systems. For a process to start the execution of a different program, it first forks to create a copy of itself. Then, the copy, called the " child process ", calls the exec system call to overlay itself with the other program: it ceases execution of its former program in ...
The Rabbit (or Wabbit) virus, more a fork bomb than a virus, is written. The Rabbit virus makes multiple copies of itself on a single computer (and was named "rabbit" for the speed at which it did so) until it clogs the system, reducing system performance, before finally reaching a threshold and crashing the computer.

Modern scheduling algorithms normally contain code to guarantee that all processes will receive a minimum amount of each important resource (most often CPU time) in order to prevent any process from being subjected to starvation. In computer networks, especially wireless networks, scheduling algorithms may suffer from scheduling starvation.
In C++, because dereferencing a null pointer is undefined behavior, compiler optimizations may cause other checks to be removed, leading to vulnerabilities elsewhere in the code. [29] [30] Some lists may also include race conditions (concurrent reads/writes to shared memory) as being part of memory safety (e.g., for access control).
Resource exhaustion attacks are computer security exploits that crash, hang, or otherwise interfere with the targeted program or system.They are a form of denial-of-service attack but are different from distributed denial-of-service attacks, which involve overwhelming a network host such as a web server with requests from many locations.
In the C and C++ programming languages, unistd.h is the name of the header file that provides access to the POSIX operating system API. [1] It is defined by the POSIX.1 standard, the base of the Single Unix Specification, and should therefore be available in any POSIX-compliant operating system and compiler.
