A Stale Record Of The Device Was Found In The Redirector. _verified_ May 2026

Here’s a deep technical and operational review of the issue: 1. Problem Definition A stale record means the redirector (e.g., a load balancer, proxy, or traffic redirector like HAProxy, Nginx, or a cloud NAT/forwarding component) still holds an outdated entry for a device’s network location (IP + port or hostname) that is no longer valid, reachable, or active.

Fix:

backend devices server device1 10.2.3.4:8080 check inter 5s rise 2 fall 3 Stale if device1 moves to 10.2.3.5 . a stale record of the device was found in the redirector.

server device1 device1.local:8080 check resolvers mydns A stale device record in a redirector is a state inconsistency problem caused by missing deregistration, long TTLs, or broken health checks. It degrades availability and misdirects traffic. The fix involves immediate manual cleanup, then implementing TTL reduction, health checks, and a device heartbeat/deregistration protocol. Long-term, shift to service discovery with real-time consistency. Here’s a deep technical and operational review of
