derrrors

Derrrors is a fictional term used in discussions of software reliability and user experience to describe a class of errors that arise when an initial fault triggers recursive or cascading error handling, producing repeated, often escalating, error messages. The term emphasizes both the error and the noisy propagation patterns that complicate debugging.

Origin and scope: The term appears in online forums and speculative writing around software resilience, where developers debate how errors propagate through layers of services and interfaces. Orthographically, derrrors often feature extra r’s to signal redundancy and emphasis.

Characteristics: Derrrors are typified by recursive failure loops, duplicate or cascading logs, and user-visible error chatter, which can mask the root cause. They may arise from non-idempotent error handlers, circular exception propagation, or retries without backoff.

Causes: Misconfigured exception handling, logging storms, retry storms, and tight error-to-user messages. In distributed systems, derrrors can be amplified by service meshes, circuit breakers, and poor observability.

Examples: A login failure triggers a generic error page that re-triggers the same process, generating a flood of identical messages in logs and alerts and obscuring the underlying problem.

Mitigation: Practices include clear error boundaries, fail-fast strategies, idempotent operations, backoff on retries, structured logging, and effective alerting that filters noise and surfaces the root cause.
