Terms for software failures

Different terms to describe what happens when software fails with the Chinese meanings from the PowerWorld following behind:

defect 过失, 缺点   

variance 不一致, 变化, 变异, 变迁, 分歧, 不和  

fault 过错, 缺点, 故障, 毛病

failure 失败, 失败者, 缺乏, 失灵, 故障, 破产, 疏忽

problem 问题, 难题

inconsistency 矛盾

error 错误, 过失, 误差

feature 面貌的一部分(眼,口,鼻等)特征, 容貌, 特色, 特写

incident 事件, 事变

bug 程序缺陷、臭虫  电脑系统或者程序中存在的任何一种破坏正常运转能力的问题或者缺陷

anomaly不规则, 异常的人或物

etc.

Problem, error and bug are probably the most generic terms used.

Fault, failure and defect tend to imply a condition that's really severe, maybe even dangerous.

Anomally, incident and variance are often used to infer unintended operation rather than all-out failure.
