To troubleshoot stalled Laravel Horizon queue jobs, inspect the Horizon dashboard for pending or failed jobs, check supervisor or systemd worker logs for crash reports, and examine Redis or database queue backends for retry loops to identify the root cause.

The best way to find N+1 queries causing slow Laravel routes is to analyze database query logs, identify repeated model retrieval patterns, and apply eager loading fixes or recommend database indexes to optimize slow operations.

To locate silent 500 errors in a Laravel production application, systematically inspect Nginx access and error logs, PHP-FPM pool logs, and Laravel storage logs to surface the underlying failures and trace root causes.

Yes, you can diagnose memory leaks in PHP-FPM Laravel applications by monitoring worker memory consumption logs, profiling application performance checkpoints, and inspecting queue workers for looping jobs that exhaust allocated memory limits.

Laravel Horizon workers disappear under heavy load when supervisor or systemd processes crash due to memory exhaustion, uncaught exceptions in looping jobs, or Redis queue backend timeouts, requiring log inspection and configuration adjustments.

When Laravel queue workers crash without application log entries, check supervisor or systemd service logs for process termination signals, inspect PHP-FPM error logs, and review Redis backend connection stability for silent retry loops.
