My AI App Crashes Randomly or Shows Error Pages
Your app works most of the time but randomly crashes, shows error pages (like 500 Internal Server Error), or becomes unresponsive. It's hard to reproduce because it doesn't happen every time.
Common Causes
- Unhandled null/undefined values — the app crashes when data is missing
- Memory leaks — the app uses more and more memory until it crashes
- Database connection pool exhausted — too many connections open
- Race conditions — multiple operations happening simultaneously cause conflicts
- Server running out of resources on a small hosting plan
How to Fix It
- Check server logs around the time of the crash for the actual error
- Monitor memory usage — if it grows over time, there's a memory leak
- Check database connection counts — they should stay within your pool limit
- Add error boundaries and try-catch blocks to prevent the entire app from crashing
- If using a free tier hosting plan, check if you're hitting resource limits

Get HelpFrequently Asked Questions
The app works fine most of the time but randomly crashes. Why?
Intermittent crashes are usually caused by unhandled edge cases — missing data, exhausted connections, or memory leaks. A developer can add proper error handling and fix the root cause.
Can you make my app more stable overall?
Yes. A developer can add error handling, monitoring, and fix underlying issues that cause instability.
