Redis Rejected Connections Incident

Back to Runbooks


This incident type refers to a situation where Redis, a popular in-memory data structure store, has rejected connections. This could happen due to various reasons such as server overload, network issues, or misconfiguration. When this occurs, it can cause disruptions in the performance of applications that rely on Redis for data storage or caching. Thus, it requires immediate attention and resolution to minimize the impact on the applications and users.
