Software aging
From both an academia and industry point of view, the software aging phenomenon has increased. The main focus has been to understand its effects from a verifiable observation and theoretical understanding.
''"Programs, like people, get old. We can't prevent aging, but we can understand its causes, take steps to limit its effects, temporarily reverse some of the damage it has caused, and prepare for the day when the software is no longer viable."''
In software engineering, software aging is the lifespan of software. As the software gets older it becomes less immune and will eventually stop functioning as it should, therefore rebooting or reinstalling the software can be seen as a short term fix. A proactive fault management method to deal with the software aging incident is software rejuvenation. This method can be classified as an environment diversity technique that usually is implemented through software rejuvenation agents (SRA).
Memory bloating and leaking, along with data corruption and unreleased file-locks are particular causes of software aging.
