In engineering, debugging is the process of finding the root cause, workarounds and possible fixes for bugs.. For software, debugging tactics can involve interactive debugging, control flow analysis, log file analysis, monitoring at the application or system level, memory dumps, and profiling.
Ambulance delays and other problems were caused by the introduction of the system. More than 30 people may have died as a result, making it the largest computer-related disaster until the downing of Boeing 737 MAX planes in 2019. The Chief of the London Ambulance Service resigned as a result of the problems and the adverse publicity. £1.5m ...
Radiation therapy planning software RTP/2 created by Multidata Systems International could incorrectly double the dosage of radiation depending on how the technician entered data into the machine. At least eight patients died, while another 20 received overdoses likely to cause significant health problems (November 2000). [18]
A software bug is a design defect in computer software. A computer program with many or serious bugs may be described as buggy . The effects of a software bug range from minor (such as a misspelled word in the user interface ) to severe (such as frequent crashing ).
In aspect-oriented software development, cross-cutting concerns are aspects of a program that affect several modules, without the possibility of being encapsulated in any of them. These concerns often cannot be cleanly decomposed from the rest of the system in both the design and implementation, and can result in either scattering ( code ...
Common exceptions include an invalid argument (e.g. value is outside of the domain of a function), [5] an unavailable resource (like a missing file, [6] a network drive error, [7] or out-of-memory errors [8]), or that the routine has detected a normal condition that requires special handling, e.g., attention, end of file.

Software maintenance is the modification of software after delivery. Software maintenance is often considered lower skilled and less rewarding than new development. As such, it is a common target for outsourcing or offshoring. Usually, the team developing the software is different from those who will be maintaining it.
In computing, a crash, or system crash, occurs when a computer program such as a software application or an operating system stops functioning properly and exits. On some operating systems or individual applications, a crash reporting service will report the crash and any details relating to it (or give the user the option to do so), usually to ...
