Automatic Queue Recovery for Media Servers

Problem Context

Media server admins run Arr stack (Radarr/Sonarr) to download and transcode movies/shows. When services shut down for maintenance or crashes, new requests from users (via Seerr or other apps) get lost because there’s no persistent queue. This breaks the workflow and causes missed downloads, wasted time, and frustrated users.

Pain Points

Users must manually restart services and requeue lost requests, which is time-consuming and error-prone. Current workarounds (like shutting down services during calls) don’t solve the root problem—requests still disappear. Without a solution, admins either accept downtime or spend hours fixing broken queues, which disrupts media delivery for the entire household or team.

Impact

Lost downloads mean missing new releases or user requests, which can frustrate family members or remote viewers. The time spent manually recovering queues adds up to hours per week, and the risk of permanent data loss (if requests aren’t requeued) creates unnecessary stress. For admins who rely on automation, this breaks the ‘set and forget’ workflow they depend on.

Urgency

This problem can’t be ignored because it directly impacts media availability—users notice when their requested content doesn’t appear. Admins who shut down services frequently (e.g., for noise reasons) face it daily, and even rare crashes can cause hours of recovery work. Without a fix, the risk of missed downloads or broken workflows grows with the number of users and services.

Target Audience

Home media server admins, small teams running Arr stack for remote users, and power users who rely on automated downloads. This affects anyone using Radarr/Sonarr with Seerr or similar request systems, especially those with multiple users (e.g., families, friend groups, or small businesses). It’s also relevant to sysadmins managing media servers for clients.

Solution Approach

A lightweight message broker wrapper that sits between Arr stack services and request apps (like Seerr). It captures all incoming requests, even when services are down, and automatically requeues them when services restart. The tool is designed as a Docker container for easy deployment and integrates seamlessly with existing Arr stack setups via API.

Key Features

1. Auto-Recovery: Monitors Arr stack services and requeues pending requests as soon as they’re back online.
2. User Notifications: Alerts admins via email or app when requests are recovered or if issues persist.
3. Docker-First Deployment: One-click setup with no admin permissions needed, ensuring zero-touch onboarding.

User Experience

Admins install the tool once (via Docker) and forget about it. When services shut down, requests are safely stored and requeued automatically on restart. Users see their requests processed without delays, and admins get notifications if anything goes wrong. The tool runs silently in the background, requiring no manual intervention—just like the rest of the Arr stack.

Differentiation

Unlike manual workarounds or generic message brokers (like RabbitMQ), this tool is *built specifically for Arr stack- and handles the unique failure modes of Radarr/Sonarr. It’s lighter than full-fledged brokers, easier to deploy than self-hosted solutions, and more reliable than duct-tape fixes. The Docker-first approach ensures it works on any system, from Synology NAS to high-end PCs.

Scalability

Starts as a single-server tool but scales to teams with seat-based pricing. Admins can monitor multiple servers from one dashboard, and the tool supports API integrations for custom workflows. Future updates could add features like priority queuing, analytics, or multi-server syncing for larger setups.

Expected Impact

Eliminates lost requests and manual recovery work, saving admins hours per week. Ensures media is always available for users, reducing frustration and support requests. The tool pays for itself quickly by preventing downtime and missed downloads, making it a no-brainer for anyone running Arr stack seriously.
