This one comes straight from the trenches.
A few days ago, my n8n webhooks completely stopped processing.Hundreds of automations.Massive execution backlog. No obvious error 😬
So I recorded a deep-dive walkthrough showing exactly how I diagnosed and fixed it.
🎥 What you’ll learn in this video:
- Why multiple n8n instances were silently killing my webhook processing
- How I implemented a single check using Postgres so only ONE instance can run at a time
- The exact workflow pattern I now use (you can copy it directly)
- How and why I added timeout limits to workflows
- A daily cron job that automatically detects & cleans up stale executions
- Why send-and-wait emails can block automations for weeks if you don’t cap them
👉 This isn’t theory — this is the production-safe setup I’m running now.
Bonus:
I’m sharing the actual workflow so you can drop it into your own system and protect yourself from the same failure mode.
If you run n8n in production…
This is one of those “set it once or regret it later” things. Future you will thank you for setting this up now.
